Exam Questions Papers

Consider the following

Maximum energy of electrons liberated photoelectrically is independent of light intensity

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

ANS:A - (1) is true and (2) is false

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

F₁ > F₂ > F₃ j = light intensity = constant Photocurrent V_s Anode voltage with frequency and incident light as a parameter. The light intensity is constant.
