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؟
Answer: Frequency of the light used
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.
