An electron is ejected from a metal via. radiation illumination above a cutoff frequency, which is specific to each metal in the photoelectric effect. Without considering any further details beyond what is mentioned above, answer parts (a) and (b).

(a) Why is this effect in conflict with classical physics?

(b) Why does the most energetic electron ejected from the metal depend on the frequency of the light and is independent of the intensity.

(c)Light with photon energy (Ephoton) and wavelength (λ), illuminates a metal with cutoff wavelength λc=2λ.

What is the maximum energy of the ejected electron in terms of Ephoton?

(d) Why was Einstein skeptical about his explanation of the photoelectric effect?
