When light hits a surface of a vacuum photocell with light of wavelength 555 nm electrons are barely ejected from the surface. You change the excitation wavelength to 401 nm. Calculate the ejected electrons kinetic energy and velocity.
I would need the complete solution to understand the answer. Many thanks
