Which of these was NOT a difficulty initially met in explaining the photoelectric effect? a. If light is a wave, its amplitude should have governed the energy imparted to electrons to cause their emission, and frequency should have had the effects it had. b.

Increased frequency of the light increased the maximum kinetic energy of the...
