QUESTION #5 De Broglie Wavelength of Electron
A photo-emissive substance is illuminated with a radiation of wavelength lambda_i so that it releases electrons with de-Broglie wavelength lambda_c The longest wavelength of radiation that can emit photoelectron is lambda_0. Expression for de-Broglie wavelength is given by: (m: mass of the electron, h: Planck's constant and c: speed of light) [cite: 39, 41]
