Learn about Einstein's photoelectric equation and work function through a comprehensive video on Khan Academy, a platform for free world-class education.
Explaining the photoelectric effect using wave-particle duality, the work function of a metal, and how to calculate the velocity of a photoelectron.

Let's explore how the graph of stopping potential vs frequency can be used to calculate the Planck's constant experimentally! From Einstein's photoelectric equation, this graph is a straight line with the slope being a universal constant. This slope has the value of h/e.
Light of wavelength 430 nm is incident on each of the metals given in the table. We will explore how to predict which of the metals will show photoelectric emission.
Explaining the experiments on the photoelectric effect. How these experiments led to the idea of light behaving as a particle of energy called a photon.
Let's explore various graphs of photoelectric experiment, and see how changing intensity and frequency changes the graphs.
Light of wavelength 430 nm is incident on each of the metals given in the table. We will explore how to predict which of the metals will show photoelectric emission.
