There are two sources of light, each emitting with a power of 100 W. One emits X-rays of wavelength 1 nm and the other visible light at 500 nm. Find the ratio of number of photons of X-rays to the photons of visible light of the given wavelength?
Hint: The energy of photons depends on the wavelength of the rays.
Step 1: Find the ratio of photons.
Suppose the wavelength of X-rays is , and the wavelength of visible light is .
Also, represents the number of photons of X-rays and visible light emitted from the two sources per sec.
