In a photoelectric experiment, the wavelength of the light incident on a metal in changed from 300 nm to 400 nm. The decrease in the stopping potential is close to
View answer and explanation
Correct option: D
1.0 V
Option D (1.0 V) is correct because the decrease in stopping potential is calculated using the change in wavelength and the given constant.

In photo-electric effect, when graph is plotted for stopping potential versus frequency of incident light, for different metals, then:
View answer and explanation
Correct option: C
The slope is universal constant equal to
Option C is correct. The slope of the stopping potential versus frequency graph in the photoelectric effect is a universal constant equal to Planck's constant divided by the elementary charge (h/e).
