Here's a breakdown:
* Moving Towards the Source: As the object approaches the source, the waves are compressed, resulting in a shorter wavelength and higher frequency. This is perceived as a higher pitch in sound waves and a blue shift in light waves.
* Moving Away from the Source: As the object moves away from the source, the waves are stretched out, resulting in a longer wavelength and lower frequency. This is perceived as a lower pitch in sound waves and a red shift in light waves.
Key Points:
* The Doppler effect applies to all types of waves, including sound waves, light waves, and water waves.
* The amount of shift in frequency and wavelength depends on the speed of the object relative to the source.
* The Doppler effect is used in many applications, such as radar, sonar, and astronomy.
