Ultraviolet light of wavelength 300 nm and intensity 1.0 Wm-2 falls on the surface of a photosensitive material. If one percent of the incident photons produce photoelectrons, then the number of photoelectrons emitted from an area of 1.0 cm2 of the surface is nearly p × 1012 s-1. The value of p is (Nearest integer)
    Correct answer is '2'. Can you explain this answer?

    Power is given by:
    Intensity of light, I = Power per unit area
    Hence, the number of photons emitted in area of 1cm2 per second is given by:
    As only 1 percent of photons produce photoelectrons, the number of electrons emitted per sec is:
    ne = 1.5 × 1012 s-1
    ne ≈ 2 × 1012 s-1
