In photoelectric effect experiment, the stopping potential for incident light of wavelength 4000 Å, is 3V. If the wavelength is changed to 2500 Å, the stopping potential will be

Options

A. 3 V
B. more than 3 V
C. less than 3 V
D. Zero volt

Answer

B

Explanation

Slopping potential `prop v`
if `lambda` is decreased , v will increase.
