Photon Z has 6x times BE+11 coolest object? the frequency of Photon X. Which of the following is TRUE about A. Photon Z? monus Intensity or Power (kW) 6E+11 E A. Photon Z has 6x the amplitude of Photon X me B . Photon Z has the same amplitude as Photon X 14. Our sun has a surface Photon Z has the same wavelength as Photon X 4E+11 temperature of 5,800 Kelvins Uow Photon Z has 6x the wavelength of Photon X and a peak wavelength of about 500 nm. Which line is Photon Z has 1/6x the wavelength of Photon X 2E+11 most likely to represent our sun? 20: Imagine two new photons of light, W and G. Photon W has 1/2 A the wavelength of Photon G. Which of the following is NOT true imuo monos 500 1000 1500 2000 about Photon W? Wavelength / nm By 4C - Own work based on JPG version Curva Planck TT.jpg, CC BY-SA 3.0, A.
