Question

(a) Calculate the wavelength of light in vacuum that has a frequency of 5.0 x 10^4 Hz. 6000 m (b) What is its wavelength in glycerine? (The index of refraction of glycerine is 1.473.) m (c) Calculate the energy of one photon of such light in vacuum. Express the answer in electron volts. Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. eV (d) What is the properties of and effect on the energy of the photon when it enters the glycerine? (Select all that apply.) the energy is proportional to the frequency the energy goes up the energy is not proportional to the frequency the energy is inversely proportional to the frequency the energy goes down the energy does not change

Explanation / Answer

energy = h x frequency = 6.626 x 10^-34 x 5 x 10^4 / 1.6 x 10^-19 = 2.07 x 10^-10 eV
