Doppler Effect Wavelength in front Calculator

Doppler effect is the change in wave length before and after an object passes the observer. The waves could be sounds waves or light waves. You could observe Doppler effect when a car coming towards you might hear different and the same car would sound different after it passes you. This happens because there is change in sound wave length. Below calculator helps you find the wavelength in front of a moving source with step by step explanation.
