The wavelength of electromagnetic radiation is doubled. What will happen to the energy of the photons of the new radiation ?

If the wavelength of an electromagentic radiation is doubled, what will happen to (i) the energy of photons and (ii) the momentum of photon?

If the wavelength of electromagnetic radiation is doubled, what happens to the energy of photon ?

When the wavelength of radiation falling on a metal is changed from 500 nm to 200 nm, the maximum kinetic energy of the photo electrons becomes three times larger. The work function of the metal is close to :
