In your own words, describe the Doppler effect. Be sure to give at least one example of the Doppler effect.

Answer and Explanation:

The process of change in the frequency due to change in distance between the source and observer is known as Doppler effect.

There are two parts in this effect either change in frequency due to change in relative motion of source and observer in same direction or change in frequency due relative motion of source and observer in opposite direction.

Example of Doppler effect

The best example of Doppler effect is that the frequency of sound increases when source comes closer to observer.

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
