Question

$\begin{array}{cccc}& \text{List-I}& & \text{List-II}\\ \left(I\right)& \text{Work function}& \left(P\right)& \text{Wavelength of photon used}\\ & & & \text{less than threshold wavelength}\\ \left(II\right)& \text{Threshold frequency}& \left(Q\right)& \text{Photo intensity of light}\\ \left(III\right)& \text{Stopping potential}& \left(R\right)& \text{number of photons}\\ \left(IV\right)& \text{Photo current}& \left(S\right)& \text{Metal}\\ & & \left(T\right)& \text{Electron}\\ & & \left(U\right)& \text{Surface of liquid}\end{array}$

• A. $I-T;II-U;III-R,S;IV-Q,R$
• B. $I-S;II-R,T;III-R,S;IV-P$
• C. $I-S;II-S;III-P,S;IV-Q,R$
• D. $I-T,P;II-S;III-T,P;IV-Q,R$

Answer 1

The correct option is C $I-S;II-S;III-P,S;IV-Q,R$

I) work function depends only on the metal.
II) Threshold frequency also depends on the metal.
III) stopping potential depends kinteic eneryg which depends on the metal well as wavelength of the light used.
IV) it depends on the number of photons and also the intensity of light.
