(i) Write a similar algebraic equation, with E as the subject, which could be used to calculate the energy of a photon of light from its frequency, f, measured in MHz, and the speed of light, c, measured in m s-1. (Do not substitute numerical values for f or c). (Note that to input your equation you should use the * symbol for multiplication and / for division, for example x * y / z.) E = (ii) Use your equation to calculate the energy in ev of a photon of yellow light with frequency 5.17 x 1014 Hz. Take the speed of light to be 3.00 x 10" m s- and give your answer to 3 significant figures. Energy: ev Check 18:18 O Type here to search 03/06/2022
