(a) How many minutes does it take a photon to travel from the Sun to the Earth? (b) What is the energy in eV of a photon with a wavelength of 558 nm? (c) What is the wavelength of a photon with an energy of 1.00 eV?

a. $\text { Thus a photon takes } 8.34 \text { minutes to travel from the sun to the earth. }$

b. $\text { The energy of a photon of wavelength } 558 \mathrm{nm} \text { is } 2.2 \mathrm{eV} \text { . }$

c. $\text { The wavelength of a photon of energy } 1.00 \mathrm{eV} \text { is } 1.24 \mu \mathrm{m}$

Let's say this is the sun and this is art. So in about Avery had us to find how much time it takes for a photo intradermal from sun to earth. Let's say this is a photo. We can find their time. Time will be simply distance divided by speed off light. Um, distance we have is 1.5 times sent a power 11 meter and speed of light is three times from the power, eight meters per second. So t will be divided by be so substituting those values. Here we get the diamond for 500 seconds which is equal to eight on 34 minutes. So he takes a 0.38 point 34 minutes for a light or a 44 tone to travel from sun to part. But be the energy will be cool to etch CD right by Lunda We're lambda given me Here is 550 pay to return, so an urgent will be simply 6.626 times Think about our minus 34 is upon Constance time Speed of flight three down Stint Our eight divided by Lunda 558 millimeter. Converting into meters this gives us energy off 2.2 electron world. We can work to the Joel, um, jewels from Jules to electron balls by dividing this answer by 1.6 times. Sentebale minus 19. There we got 2.2 electron Walt. But see the land out from Fort Owen will be prevalent off for time will be its see divide by energy. Um, so it's a student rally six for six to six times Interpol minus 34 times three times, then to power eight. Divided by energy, that is. Ah, 1.6 times 10 to the power minus 19. Jules, this gives us a 1.24 times an hour, minus six meter logistical to 1.24 micro meter. Um, so one electron world has got the energy. It's going to be able in tow for 1.24 micro meter
