Disscuss Question 8204 of Exam Questions Papers - Exam Paper 1 of Electronics and Communication Engineering :: Electronics & Communication Engineering

1. 

Consider the following

1.Maximum energy of electrons liberated photoelectrically is independent of light intensity

2.Maximum energy of electrons liberated photoelectrically varies nonlinearly with frequency of incident light.

 
[A]. (1) is true and (2) is false
[B]. (1) and (2) both are true
[C]. (1) is false and (2) is true
[D]. (1) and (2) both are false

Answer: Option A

Explanation:

Statement (ii) is false because maximum energy of photons varies linearly with frequency of incident light. It can be shown as follows :

2-762-24-1

F1 > F2 > F3

j = light intensity = constant

Photocurrent Vs Anode voltage with frequency and incident light as a parameter.

The light intensity is constant.
