142020 When a metallic surface is illuminated by a light of wavelength $\lambda$, the stopping potential for the photoelectric current is $3 \mathrm{~V}$. When the same surface is illuminated by light of wavelength $2 \lambda$, the stopping potential is $1 \mathrm{~V}$. The threshold wavelength for this surface is
142021 In a photoelectric effect measurement, the stopping potential for a given metal is found to be $V_{0}$ volt when radiation of wavelength $\lambda_{0}$ is used. If radiation of wavelength $2 \lambda_{0}$ is used with the same metal then the stopping potential (in volt) will be :
