5. A light wavelength 5.0 x 10−7 m is incident on metal resulting in photoemission of electrons. If the work function of the metal is 3.04 x 10−19J, calculate the:

(i) frequency of the light

(ii) energy of the incident photon,

(iii) maximum kinetic energy of the photoelectrons (Speed of light = 3.00 x 10^8ms−1; Planck's constant = 6.6 x 10−34Js).?
