Question

a metal surface of threshold frequency 5.3×10^14 sec is exposed to a photon of radiatio having energy 3.4×10^-19J fi d the velocity of electrons​

Answer 1

Answer:

Explanation:

When a photon hits the metal surface, the photon's energy is absorbed by an electron in the metal. The graphic below illustrates the relationship between light frequency and the kinetic energy of ejected electrons. The effects of wave frequency on photoemission. The frequency of red light (left) is less than the threshold frequency of this metal (ν red < ν 0) (\nu_\text{red}<\nu_0) (ν red < ν 0 ) left parenthesis, …
