NEET Physics Question - Modern Physics - Photoelectric Effects and deBroglie Equation

Assertion (A): Photoelectric effect demonstrates the wave nature of light.

Reason (R): The number of photoelectrons is proportional to the frequency of light.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

The photoelectric effect experimentally supports the particle (photon) nature of light, not its wave nature. The number of photoelectrons emitted is directly proportional to the intensity of incident light, not its frequency. Therefore, both assertion (A) and reason (R) are false.
