Reference no: EM13313406

Ultraviolet light is shone on a particular metal and the stopping potential is measured at the same time. It is found that 2.64 V is needed to stop all the electrons when the wavelength of the light is 295 nm, and 4.76 V for a wavelength of 214 nm.

What is the work function of the metal?

What is Planck's constant based on this measurement?
