141973 A metallic surface is illuminated with radiation of wavelength $\lambda$, the stopping potential is $V_{0}$. If the same surface is illuminated with radiation of wavelength $2 \lambda$, the stopping potential becomes $\frac{V_{0}}{4}$. The threshold wavelength for this metallic surface will be.
141977 The threshold frequency of a metal is $f_{0}$. When the light of frequency $2 f_{0}$ is incident on the metal plate, the maximum velocity of photoelectrons emitted is $v_{1}$. When the frequency of incident radiation is increased to $5 f_{0}$, the maximum velocity of photoelectrons emitted is $v_{2}$. The ratio of $v_{1}$ to $v_{2}$ is:
