Question 161: Dual Nature of Matter and Radiation

Question

In a photoelectric effect experiment, the graph of stopping potential V versus reciprocal of wavelength
obtained is shown in the figure. As the intensity of incident radiation is increased :

Accepted Answer

eV = $${{hc} \over \lambda } - \phi $$
$$ \Rightarrow $$ V = $$\left( {{{hc} \over e}} \right){1 \over \lambda } - {\phi  \over e}$$
Slope of the line in above equation and all other terms are independent of intensity. The graph does not
change.

Answer

Slope of the straight line get more steep

Answer

Graph does not change

Answer

Straight line shifts to left

Answer

Straight line shifts to right
