A
In photoelectric effect, there are ejection of electrons from metal surface when radiation strikes it.
B
The number of electrons ejected is proportional to the intensity or brightness of light.
C
Photoelectric effect is observed below threshold frequency.
D
At a frequency 
, the ejected electrons come out with certain kinetic energy.
, the ejected electrons come out with certain kinetic energy.
Text Solution
Verified by ExpertsThe correct answer is:
C
For each metal, there is a characteristic minimum frequency, 
(which is also known as threshold frequency) below which photoelectric effect is not observed.
