Hope this helps you.......^_^

Answer 2

Answer:

Threshold frequency is the minimum frequency and work function is the minimum amount of energy required to remove an electron from the metal surface.

Explanation:

Threshold frequency is the minimum frequency required to remove an electron from the surface of the metal.This frequency is required in the photoelectric effect.

Photoelectric work function is the minimum energy required to remove the electron from the metal surface.

we know the Einstein energy equation for the photoelectric effect

$h\vartheta =h\vartheta _{o} +\frac{mv^{2} }{2}$

Here $\vartheta _{o}$ = Threshold frequency ,  $h\vartheta _{o}$ = photoelectric work function.
