what is the formula for calculating the wavelength of light depending on frequency or velocity
For photoelectric emission, tungsten requires light of 2300 ∘A. If light of 1800 ∘A wavelength is incident then emission
Light of wavelength 5000 Å falls on a plane reflecting surface. What are the wavelength and frequency of the reflected light? For what angle of incidence is the reflected ray normal to the incident ray?
