Question

Light of frequency, v is incident on a certain photoelectric substance with threshold frequency v0. The work function for the substance is: (A)  hv  (B)  hv0  (C)  h(v-v0)  (D)  h(v+v0)

The minimum energy required for the emission of photoelectrons from the surface of metal is known as work function of the metal, and the frequency corresponding to work function is known as threshold frequency.
Work function

= h v_{0}

where

v_{0}

is threshold frequency.

Q. Light of frequency, $v$ is incident on a certain photoelectric substance with threshold frequency $v_{0} .$ The work function for the substance is:

$h v$

$h v_{0}$

$h (v - v_{0})$

$h (v + v_{0})$

The minimum energy required for the emission of photoelectrons from the surface of metal is known as work function of the metal, and the frequency corresponding to work function is known as threshold frequency.
Work function $= h v_{0}$ where $v_{0}$ is threshold frequency.
