Assertion : The threshold frequency of photoelectric effect supports the particle nature of light.
Reason : If frequency of incident light is less than the threshold frequency, electrons are not emitted from metal surface.

Assertion : The threshold frequency of photoelectric effect supports the particle nature of sunlight . Reason : If frequency of incident light is less than the threshold frequency , electrons are not emitted from metal surface.

The threshold frequency of a photoelectric effect depends on

What is threshold frequency in the photoelectric effect?

What is threshold frequency in connecting with photoelectric effect?

Threshold frequency for photoelectric effect from a metal surface of work function 4.5 eV is

Using Einstein.s photoelectric equation show that photoelectric emission is not possible if the frequency of incident radiation is less than the threshold frequency

Statement I : Threshold frequency supports wave nature of light. Statement II : Photo electrons are not emitted when incident light has frequency lesser than threshold frequency.

Explain- The role of threshold frequency is photoelectric effect is ini agreeement withh the particle nature of light and in disagreement with the wave nature of light.

Assertion : Photoelectric effect demonstrates the wave nature of light. Reason: The number of photoelectrons is proportional to the frequency of light.
