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

    any photons of higher energy than green

    none of the visible ones. Some ultraviolet ones would be capable of ejecting two or more electrons from the same metal
