Answer
D. A, B, D and E Only
$\lambda=\frac{C}{v}=\frac{3 \times 10}{5.16 \times 10^{14}}$
$\lambda=581.39 \mathrm{~nm}$
→ $\lambda_{\text {Photon }}$ is near & below yellow light it can show photoelectric effect.
→ If intensity of light decreases photocurrent decreases.
→ Red light will not produce photoelectric effect.
→ $v_{\text {Blue }}>v_{\text {yellow }}$ so photoelectric current will be produced.
→ White light contain all frequencies so it will show photo electric current.
Correct statements are $\mathrm{ABD}$ $\&$ $\mathrm{E}$.
