The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states: "Photoelectric effect is the phenomenon of emission of photon by metal when illuminated by light of suitable frequency." - This definition is incorrect because the photoelectric effect refers to the emission of electrons (not photons) from a metal when it is illuminated by light of a suitable frequency. Therefore, the assertion is **false**. 2. **Understanding the Reason**: - The reason states: "An electron beam carries sufficient energy to release photons from the metal." - This statement is also incorrect. An electron beam does not release photons from the metal; rather, it can cause the emission of electrons if the energy is sufficient. The correct statement would be that photons (light) of sufficient energy can release electrons from the metal surface. Therefore, the reason is **false**. 3. **Conclusion**: - Since the assertion is false and the reason is also false, we conclude that both statements are incorrect. ### Final Answer: - The assertion is false, and the reason is false.

Assertion : Photoelectric effect supports the quantum nature of light. Reason : Photoelectric emission is instantaneous.

Assertion: Photoelectric effect proves the particle nature of light. Reason: Photoemission starts as soon as light is incident on the metal surface, provided frequency of incident light is greater than or equal to the threshold frequency.

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.

In photoelectric effect when photons of energy hv fall on a photosensitive surface (work function hv^) electrons are emitted from the metallic surface with a kinetic energy. It is possible to say that:

Assertion : The number of electrons ejected from a metal surface depend upon the frequency of light. Reason : There is a time lag between the striking of light beam and the ejection of electrons from the metal surface.

Assertion : If the frequency of the incident light on a metal electrons is more than doubled. Reason : The metal will provide additional energy to the emitted photoelectron for light of higher frequency than for lower frequency.
