Episode 4 — Waves Sound and Light - Doppler

Waves, Sound and Light

Learners will be able to:

• Explain the Doppler effect and its application in various fields such as medicine, military, and astronomy. • Describe how the frequency of a wave changes when the source is moving relative to an observer or vice versa. • Identify the relationship between wavelength and frequency of a wave. • Calculate the change in frequency due to the movement of a source or observer using the Doppler effect principle. • Apply the Doppler shift concept to explain the observation of redshifted light from distant stars, supporting the Big Bang Theory.
