Given here is the wavelength formula astronomy to calculate λ for the given frequency. Formula is given as speed of light / frequency and it is expressed as λ = c / f, where c = speed of light (299792458 m/s) and f = frequency. The wavelength is the distance between individual waves. This astronomy wavelength formula of wavelength astronomy helps in studying the astronomical objects and their behaviour with the electromagnetic radiation (light).

Where,

C = Speed Of Light(299792458 m/s)

F = Frequency

The astronomy wavelength formula quantifying the doppler effect with speed of light. It helps in learning about the radio wavelengths observed from radio sources in the sky.
