Chemistry - Atomic Structure Question with Solution | TestHub

There is no electron ejection, regardless of intensity of the radiation unless the frequency, exceeds a threshold value which is the characteristics of metals

Kinetic energy of ejected electrons varies linearly with the frequency of incident radiation and its intensity

Even at low intensity, electrons are ejected immediately if the frequency of incident light is more than the threshold frequency

An intense and weak beam of monochromatic radiation differs in having number photons and not in the energy of photons
