Photoelectric emision occurs only when the incident light has more than a certain minimum
Options
(a) power
(b) wavelength
(c) intensity
(d) frequency
Correct Answer:
frequency
Explanation:
For occurence of photoelectric effect, the incident light should have frequency more than a certain minimum which is called the threshold frequency (v₀).
We have, 1/2 mv² = hv – hv₀
for photoelecric effect emission v > v₀ where v is the frequency of the incident light.
