If a red light matches the cut-off frequency of a metal and can liberate electrons from the metal surface. When a blue light shincs on the same metal, will you expect to observe the photoelectric effect (liberation of free electrons from metal) with this blue light? A. No, because blue light photon has lower energy due to smaller wavelength compared with the red-light photon. B. Yes, because blue light photon has higher energy due to higher frequency compared with the red light photon. C. Cannot be determined without additional information.
