Question 301: Dual Nature of Matter and Radiation

Question

If the frequency of incident radiation $(
u)$ is increased, keeping other factors constant, the stopping potential ( $
u>
u_0$, threshold frequency)

Accepted Answer

$$\begin{aligned}
&\mathrm{eV}_{\mathrm{s}}=\mathrm{h} 
u-\mathrm{W}_0\
	herefore\quad &	ext { If } 
u 	ext { increases, } \mathrm{V}_{\mathrm{s}} 	ext { will increase. }
\end{aligned}$$

Answer

increases

Answer

decreases

Answer

remains constant

Answer

suddenly becomes zero
