Dual Nature of Radiation and Matter

Question:

Options:

a

b

c

d

Correct Answer:

d

Explanation:

Let Current be

I

and intensity be

I_{i n t}

Each photon gives rise to one photoelectron. Also, intensity is proportional to incident photons and energy of each photon.

Hence,

I \propto I_{i n t}

I_{i n t} \propto E

Energy of a photon,

E = h c / λ

⟹ I \propto 1 / λ
