When radiation of wavelength \( \lambda \) is incident on a
P
metallic surface, the stopping potential is 4.8 volts.
W
If the same surface is illuminated with radiation of double the wavelength, then the stopping potential becomes 1.6 volts. Then the threshold wavelength for the surface is \( n \lambda \). Find the value of \( \mathrm{n} \)
