speed off neutron Nichols. 1200 meter per second speed off neutron. We equals 1200 meter for a second, and momentum off neutron is given by momentum off neutron equals am not times we divided by square root off one minus. Uh, we squared, divided by C Square. And also we have momentum for dawn. Momentum off foot on, and it is equal to each divided by lender and each divided by lambda can be returnees h f. Divided by sea. In the human problem, momentum of neutron is equal to momentum or foot on momentum. Off neutron. It&#x27;s equal to momentum off for tone for dawn and substituting the values we have. Am not we divided by scared Rudolph? One minus we square divided by C Square, which is Ah, momentum off neutron is equal to a momentum of foot on momentum. Off. Put on is H F, divided by sea and solving for F. We have F equals F equals. I am not multiply by. We multiply. They see, divided by each multiply rights were Rudolph one minus Reece squared, divided by C Square. Let&#x27;s plug in the values. No f equals, um Barcelo Neutron. Most of neutron ease 1.674 Multiply by 10 to the power minus 27. Multiply by velocity. They&#x27;ve lost two of new cronies, 1200 meter for a second, multiplied by speed of light, which is a three. Multiply by 10 to the power eight meters per second. Divided by, uh divided by ah plan Constant 6.63 Multiply by 10 to the power minus Terry Fall Jules Second multiply by squared road off one minus week We&#x27;s again, uh, 1200 meter per second square. We have square divided by R C square. Pre multiply. My tend to the power eight all square and this gives us 9.1 multiplied by 10 to the power 17 hearts.

9.11 multiplied by tend to devour minus 31 kilograms. Most of the electron M e equals 9.11 one supplied by turned to the power minus 30 bon kilograms and we lost two of the electron. Li e equals 1500 mater per second and a plane constant H equals 6.63 Multiply by 10 to the power minus 34. Jule. Second, the momentum of the electron is same to the momentum off the baton. And, uh, do broccoli babble. Int lender is Cuban by edge divided by Pete It is a blank constant and beaches uh, momentum. It&#x27;s divided by B equals H divided by B P is the momentum momentum off electron Marcel&#x27;s electron times? Um, the lost two of electron solving for Lambda we have 6.63 multiply by 10 to the power minus 34 divided by most of electron ease, 9.11 multiplied by 10 to the power minus 31 kilograms multiplied by lost two of the electron is a 1500 meter per second 15 100 meter per second. Well solving. This week, it Lambda uh, is equal to four point it. 4.85 Multiply by 10 to the power minus seven meters and this can be written is for 85 Multiply. Lie time to the baller minus nine meters. Huh? Tentative Over minus mine is Meno. Therefore, we have 485 nano meters, so babble in nickels, 435 centimeters.

here. We know that four party, the rest energy of an electron is going to be given us e. This would be equal to the mass of the electron times the speed of light squared. Thus the momentum of the photonic question P would be equal to the elect the energy of the electron divided by the speed of light. So this should be an e C squared, divided by sea. And this is simply equaling the mass of the electron multiplied by the speed of light. This would be equal to 9.11 times 10 to the negative 31st kilograms and then multiplied by the speed of light 2.998 times 10 to the eighth meters per second. And we can say that the momentum then would be equal to 2.73 times 10 to the negative 22nd kilogram meter per second. And we can convert and said that this is gonna be equal 2.511 mega electron volts divided by sea. And so we can say that here for part B from equation 38 7 we can say that Lambda would then be equal to the planks constant divided by the momentum. This is gonna be equal to 6.63 times 10 to the negative, 24th Jules second. And then this would be divided by 2.73 times, 10 to the negative 22nd kilogram, a meter per second. And so this is giving us 2.43 times 10 to the negative 12th meters. Or we can say the land of the wavelength would be 2.43 pico meters and then finally, for part C using equation 38 1 we simply want to find the frequency so the frequency would simply be equal to the speed of light divided by the wavelength. This would be equal to 2.998 times 10 to the eighth meters per second. This would be divided by 2.43 times 10 to the negative 12th meters. And so the frequency would be equal two 1.24 times 10 to the 20th hurts. This would be your answer for C. Our answer for B and of course, our answer for a that is the end of the solution. Thank you for watching

Hey, hugged in. People here were given an energy of the radio wave equals to 1.55 times 10 to the power of negative 24 jewels. And we&#x27;re supposed to find the frequency of the radio wave. Here. We needed an equation to associate energy with frequency, the only one I can think on top of my head. It&#x27;s energy. You close to plans Plank&#x27;s constant times you or to frequency, rearranging the frequency so that it&#x27;s going to be on the one side. Give us immune equals two. You are energy divided by the plank&#x27;s constant. No, we have to something. The numbers with energy of 1.55 times 10 to the power negative 24 jewels very important to include the units. And we have plans constant equals to 6.63 times 10 to the power of negative 34 Jules Times a second Before we punch in a calculator, let&#x27;s check the units to make sure work anyone we want because he is going to being hurts or psychos per second. Either one is fine. I&#x27;m going to pick this one, and that&#x27;s canceled the juice, leaving only the second here. So it&#x27;s going to be one over second. Just like what you want. Now we can just punch in a calculator and we&#x27;re getting 2.34 times. Tend to a part of 91 over second. Don&#x27;t forget to Unit. Thank you so much for watching.

for the first bodies. Question. We will find the wavelength off the foot on death. The same mo mentum esti proton moving and have it all see off 1% the speed of light. So it is about low velocity, the momentum it&#x27;s giving a scum A and B because it&#x27;s, ah quite close to the spiel like So we&#x27;re gonna you see relativistic bush in EU momentum. No, What&#x27;s comma? Comma is one of over skirts or four minus discover grey. And given that it V is 0.1 to be one of us coats off one minus point to one square. All right, just the Fecteau. Quite small, but ah, stew Significant. We&#x27;re going to include that in, you know, corporations. So what is this? The momentum we have? T mess off T Proton. Just one point 66 ST Paul minus 37 kilograms, Attendee. Frosty. Two points you want see? Divided by square roots off through point 9999 So we&#x27;ll see the spiel flight going to use 2.9. I eat instead of eat just a second and the momentum is forget about 4.977 extent. Paul, Minister anyone Two comedies into with Frank for a photon. We quit this too. Ah, energy off a photo develop. I see. Yes, he close to each off under Solando Because to each divided by Pete Momentum. So it just substituting hitch the 6.626 and every putting momentum in and 60 way flanks in terms off meters Not to find the energy of this photo on. Now, the energy just each see Uh huh. But, ah, we specifically wanted to be in terms off m e v. So after the India&#x27;s corporations, you have to convert it into mutts Will be in terms off jewels, really to MTV view, have toe add in effect, er divide by 1.6 times sent home Minister teeth juice for MTV is what company into. I mean should get about nine point tree tree MTV No, to find any kinetic energy off the proton in any of you. Well, we have free will see found the momentum itself to find the kinetic energy. Since it is quite relativistic, we&#x27;re gonna use the relativistic question. Come on, minus one times m c square, where mst meself de proton so come affect er Seiko, it&#x27;s one over. Screw its office. Your 0.9999 times M c square, which in this case, you know the rest energy for a put on about nine tree point tree That may be spokes Your points you for 69 MTV. So the energy is Syria, Afghani lesser all the world, then the energy off the photo.

Sheh Lit Chang · Answer

in this question. We wants to determine their frequency of the proton. So using equals two h f and one E v iss 1.6 times 10 to the negative. 19 Jews. So the frequency de frequency equals two e over each. He goes to given that its CI v so Congress that she evening into juice about by 6.6 tree times, 10 to the negative 34 putting them into calculator. You get 7.24 times 10 to the 14. Good. Okay, so the answer, it&#x27;s this.
