There are 2 lessons in this physics tutorial covering The Doppler Effect. The tutorial starts with an introduction to The Doppler Effect and is then followed with a list of the separate lessons, the tutorial is designed to be read in order but you can skip to a specific lesson or return to recover a specific physics lesson as required to build your physics knowledge of The Doppler Effect. you can access all the lessons from this tutorial below.

In this Physics tutorial, you will learn:

• What happens to the wavelength and frequency of a wave when the source and the receiver are moving in respect to each other?
• What is the Doppler Effect in waves?
• How the Doppler Effect is applied in sound waves?
• How the Doppler Effect is applied in light waves?
• What is the general equation of the Doppler Effect in waves?

## Introduction to The Doppler Effect

Most people are able to understand whether an ambulance car is approaching or moving away from them. Are you one of those? How do you understand this?

How the sound is emitted by a moving source compared to cases in which the source is stationary?

Do you think this phenomenon exists in other kind of waves? What can you say about light?

There is a common explanation for all the above questions. It is related to the relative movement of the wave source and the receiver, which we discuss and explain in the following lessons.
