Question

ce Predict/Explain Light of a particular wavelength does not eject electrons from the surface of a given metal. (a) Should the
wavelength of the light be increased or decreased in order to
cause electrons to be ejected? (b) Choose the best explanation from
among the following: 
I. The photons have too little energy to eject electrons. To in-
crease their energy, their wavelength should be increased.
II. The energy of a photon is proportional to its frequency; that
is, inversely proportional to its wavelength. To increase the
energy of the photons so they can eject electrons, one must
decrease their wavelength.

art, eh? Huh? Part in development Off the light should be decreased in order to cause electrons to be rejected on the battle end off the light lander. Javelin. Uh, off the light off the light, uh, should be decreased. Should be ah, decreased should be decreased in order to cause electrons to be ejected. Uh, we know that e is equal to edge and, uh, see is equal lender, and it cools. See, divided by r f equals C divided by lambda and substituting f We have, ah, e equals or edge of equals Each times see divided by lender. So it&#x27;s obvious from this equation. If lambda is decreased, then the energy off for dawn increases. And then it can, uh, because electrons to be ejected from the metal surface. Uh, no legs sold. Part B. Well, in Barbie, the second option is the best explanation. Ah, the energy off for dawn is proportional to its frequency. Are these radically proportional to a frequency and that is inversely proportional to its valent. And, uh, energy is inversely proportional to, uh, babbling to increase the energy off the photons. Um, so they can eject electron one must decrease. Ah, Valent. One must decrease the, uh, prevalent. So second option is the best explanation

Zulfiqar Ali · Answer

the changing of length Delta Lander equals Lend a prime minus Lambda Lambda Prime minus lambda equals bitch divided by empty lots of electron multiplied by C, which is speed of light into one minus co sign of Peter. Here, Peter Peter is the scattering angle. Peter is the scattering angle. All right, If Peter equals 90 degrees, then we have changing. Javelin equals ich divided by months of electron time. See into one minus course I know mine. Two degrees we&#x27;ll sign off minded agree Equal is equal to, um zero. Therefore, changing babbling equals itch divided by m e multiplying. I see so changing balance equals edge divided by months of electron times the speed of flight when Peter equals 90 degrees. If Peter is zero, then we have changing. Valent equals itch divided by changing Babylon equals each divided by Marcel Electron time see into one minus one Because go sign of serious one and changing Valent is equal to zero. Sure, uh, did for change in Babel int in crazies change in that lint in crazies increases. It&#x27;s the scattering angle in quizzes from zero to 90 degrees and it feed Isaac Walton 90 degrees. Frieda is equal to 90 degrees. Change in Babel in is a maximum is maximum, so change in Valent increases is ah, scattering angle are is the scattering angle increases increases. Now let&#x27;s sold part B well, the best explanation is explanation. Number one. There&#x27;s explanation number one, and it says that a lot of scattering angle means Ah, large shirt, A larger scattering angle. Frieda means, um, a large transfer of momentum, a larger transfer off, larger transfer of momentum momentum and thus a larger change in battle. That&#x27;s a larger changing balance. Uh, march here change and you&#x27;re babbling, Well, let me see the game. Uh, a larger scattering Ingle Peter means a lot of change in momentum. So large, uh, change in momentum and a lot changing momentum means a large is changing bat linked and grab lint off the foot down. Leant over the don&#x27;t

part, eh? A maximum. Ah, kinetic energy Often rejected Electron remains the same. Maximum kinetic energy or and ejected electron remains the same. Remains the same art be, uh, the minimum de broccoli. Bad land off in electron also demands the same. So the minimum the minimum, not de Brantley Fab Lind, Often electron. Um oh, and electron remains the same. Remains the same. Artsy, the number of rejected the number of electrons ejected per second in crazies. But the number the number Oh, electrons ejected 1st 2nd burger. Second increases in crazies and body on the electric current I in the photo tube, uh, increases increases.

Zulfiqar Ali · Answer

part, eh? The maximum kinetic energy often oh, family rejected electron increases. Uh, the maximum, uh, kinetic energy. Often electron, often electron increases part B The minimum the broccoli that land lender open electron did crazies, Dick raises, and Marcie the number of electrons ejected per second. So number off electrons ejected per second or second decreases did crazies. Finally, body electric around in the photo to you also decreed it. So I electrical and in the 4 to 2 wanted to you. To you It&#x27;s to you Dick raises.

we know that Lambda equals h divided by B lettuce blanks constant in peace momentum. And this can be friend the returnees h divided by mass times. Velocity part it is. Accelerate your card away from spotlight The d probably grab lint off the car decreases. So, uh, uh, de Broca bab lint Bam Lynch Dick raises dick races. It is clear from this equation Beat There is in worse relationship between momentum and grab lint. Thank you. Uh, the more is the momentum on smaller is the javelin. Uh, Barbie? Well, in part B, uh, Option two is the best explanation. Option two is the best explanation. Best explanation. And it says that the momentum off the car increases and this follows that the differently babble into decrease because it is inversely proportional to the babbling.

Zulfiqar Ali · Answer

well, Bart a a green light. His larger frequency than blue light Therefore energy off for dawn&#x27;s emitted by the green source. So energy or photons emitted by, uh, the green source is greater than the energy or photons emitted by the reps or so is greater than on the energy off photons emitted by. Ah, the red source by the red source. Yeah, and, uh, in Barbie, our second option second option is correct. Second option is correct. Uh, the rib source four dawns have less energy than the cream source for tones because they have a lower frequency. Ah, the what? Age off. The source does not matter. We know that energy equals H f. It is a constant in Athens, the frequency, energy and frequency off a radiation is directly related your frequencies higher. Then the four tone is a large amount of energy, and the frequency is smaller than the foot on his a lesser amount of energy and therefore ah, the second explanation is the correct IQ explanation
