\sqrt{2}

\sum_{i=1}^3

\sin \theta

\boxed{123}

K is the wave number or better said as :

\(k=\dfrac{2\pi}{\lambda}\)

Where \(\lambda\) is the wavelength of the wave.

Then what is \(frac{1}{lambda}\) in Rydberg formula .are they both same pronounced

@Ronak Agarwal – Now I understood ,thanks for the link phenom

\(k\) in \(\sin(kx-wt)\) is called the \(wave\) \(number\) in physics.

@Deepanshu Gupta @Ronak Agarwal plz help
