Radiation of wavelength \(331\ \text{nm}\) irradiates the following metals :
Radiation of wavelength \(331\ \text{nm}\) irradiates the following metals :
Show Hint
For photoelectric effect questions, quickly calculate the photon energy using
\[
E(\text{eV})=\frac{1240}{\lambda(\text{nm})}.
\]
If the photon energy exceeds the work function, photoelectric emission occurs.
