A basic relation between wavelength frequency and velocity results from the following consideration. Wavelength and frequency are therefore inversely related. A video made by a student for a student.

Calculate the velocity frequency and wavelength of the sodium D line l 589 nm as light from this source passes through a species whose refractive index n D is 109. If needed convert the. For this the formula to use is f V l where f refers to the frequency V refers to the waves velocity and l refers to the waves wavelength. 3 0 0 H z.
