Question

The velocity of photon emitted in photo-electric effect depends on the properties of photosensitive surface and _______ . (A) frequency of incident light (B) state of polarization of incident light(C) time for which the light is incident (D) intensity of incident light

Answer 1

Answer:

B is correct Photo electric effect means emission of electron

Answer 2

Answer:

Option (A) is correct.

Explanation:

Since we know that the when a light of suitable frequency(Greater than the threshold frequency )falls on the metallic surface then ejection of electron is possible which leads to the photo-electric current and hence photoelectric effect is defined.

So,The velocity of photon emitted in photo-electric effect depends on the properties of photosensitive surface and frequency of incident light

So, option (A) is correct.
