The kinetic energy of an electron ejected from a metal surface exposed to monochromatic radiation depends on the at _____?

The kinetic energy of an electron ejected from a metal surface exposed to monochromatic radiation depends on the at _____?

ایک الیکٹران کی حرکیاتی توانائی جو دھات کی سطح سے نکالی گئی ہے جو مونوکرومیٹک تابکاری کے سامنے ہے _____ پر منحصر ہے؟
Explanation

According to Einstein's photoelectric equation, the kinetic energy (K) of an ejected electron depends on the frequency (f) of the incident light:

K = hf - φ

where h is Planck's constant and φ is the work function of the metal.
