Question

19. Give the Einstein's photoelectric equation and explain the terms used.
​

Answer 1

Explanation:

Each quantum has an energy h, if this energy exceeds the minimum energy to emit electron then the electron is emitted with maximum kinetic energy. Planck's constant is h = 6.62 × 10−34 joule-sec. This equation is known as Einstein's photoelectric equation.
