Dual Nature of Radiation and Matter: RE-NEET 2026

Medium· Experimental Study of Photoelectric Effect (Threshold Frequency and Wavelength)· +4 / −1

A ray of light with wavelength

\lambda

is incident on three different photoelectric cells namely 1, 2 and 3. The threshold wavelength of these photoelectric cells are

\lambda_1

\lambda_2

, and

\lambda_3

, respectively and the magnitude of stopping potentials of these cells are

V_1

V_2

and

V_3

, respectively. The relation between

\lambda

and threshold wavelengths are

\lambda_1 < \lambda

\lambda_2 > \lambda

and

\lambda_3 \gg \lambda

. The correct option is:
