A photon of green light is capable of ejecting an electron from a piece of metal. What other colors should also be capable of this?

Blue, indigo, violet, ultraviolet, x-rays and gamma rays. All if those have more energy. E = hv. h = Planck constant, v= frequency.

blue and violet

any photons of higher energy than green
and those would be from farther along the spectrum toward violet
When you get a good response,
please consider giving a best answer.
This is the only reward we get.

none of the visible ones. Some ultraviolet ones would be capable of ejecting two or more electrons from the same metalSource(s): extrapolating
