K is the wave number or better said as :

$$k=\dfrac{2\pi}{\lambda}$$

Where $$\lambda$$ is the wavelength of the wave. · 1 year, 7 months ago

Then what is $$frac{1}{lambda}$$ in Rydberg formula .are they both same pronounced · 1 year, 7 months ago

Now I understood ,thanks for the link phenom · 1 year, 7 months ago

$$k$$ in $$\sin(kx-wt)$$ is called the $$wave$$ $$number$$ in physics. · 1 year, 7 months ago
