Physics - Ch 66 Ch 4 Quantum Mechanics: Schrodinger Eqn (68 of 92) What is the Wave Number k=?

In this video I will explain what is the physical concept of the wave number “k” (k is defined as the number of radians per unit distance) in the wave equations.

Aur plz upload question on electric potential and electrifield both mixed plz

The unit of 'k' is {rad/length} or simply 1/{length}. k represent the number of wavelengths in a unit of distance of 2pi (nm). Ex: if k = 4 nm^-1; means that there are 4 wavelengths in a length of 2pi nm; in other words, the wavelength is pi/2 nm (or pi/2 rad/nm)

A little late to get the meaning of 'k'
