When a light of a given wavelength falls on a metallic surface the stopping potential for photoelect

A light radiation of photon energy 4 eV falls on a surface having the work function 2 eV. The stoppi

From the figure describing photoelectric effect we may infer correctly that:

Photon is quantum of radiation with energy E = hν where ν is frequency and h is Planck's constant. T

If a proton and alpha particle have same de-Broglie wavelength, then ratio of their respective linea
