A uniform beam of red light, with a wavelength of 6.42x10^-4 meters illuminates towards a wall that is 6.0 meters long and 5.5 meters wide. The light intensity is 7.0 x 10^-15 W/m^2.
a) What is the frequency of the light?
b)What is the uniform magnitude of rms of Erms and Brms?
c) What is the radiation force on the wall if its totally reflects all of the light back along the incident path?
