Question:medium
The threshold frequency of a metal corresponds to the wavelength of \(x\) nm. In two separate experiments ‘A’ and ‘B’, incident radiations of wavelengths \(\frac{x}{2}\) nm and \(\frac{x}{4}\) nm respectively are used. The ratio of kinetic energy of the released electrons in experiment ‘B’ to that in experiment ‘A’ is
