Frequency of light

Postby Marsenne Cabral 1A » Sat Oct 27, 2018 3:09 pm

Is there any surface that would emit electrons when the light being shown on it is visible light?

I believe there are few metallic surfaces that would emit electrons if visible light is used but the majority only get emitted if ultraviolet light is used

If the visible light's energy is greater than or equal to the work function of the metal then yes, but I can't think of a metal off the top of my head.
