Question

When uv light of wavelength falls on a metal surface the maximum kinectic energ of emittedphoto electron depend ony?

Answer 1

When we speak of a molecule as being raised to a higher electronic level we mean that an electron has been changed from one orbital to another orbital of higher energy. This electron can be of any kinds we have encountered –a σelectron, a π electron or an n electron. In Ultraviolet region we are confined only to the excitation of the comparatively loosely held n and πelectrons.
