A light of wavelength 5000 angstrom

What are the wavelength and frequency of the reflected light?

What are the wavelength and frequency of the reflected light? For what angle of incidence is the reflected ray normal to the incident ray? The wavelength and frequency of incident light is the same as that of reflected ray. When reflected ray is normal to incident ray, the sum of the angle of incidence, ang.

The number of incident photons N per second per square metre is therefore:. Here is an alternate approach. Here we assume that the work function is overcome by the incoming light energy Note that the work function was not stated, so we must assume that it is overcome by the incoming light energy The light wavelength angstroms should be represented in "m" , as Planck's constant has "m". Therefore, the energy contained in one photon of that wavelength is:. Now, the intensity of light can be treated as if it were an energy value for all the photons involved, since we retain all the units beyond "J". Jun 18, Truong-Son N.
