Doppler Effect

Mr. Anderson explains the Doppler Effect, illustrating how sound, water, and light waves change frequency due to motion. He discusses the effect of movement on wave frequency, using real-world examples like sirens and cars. The video also covers Hubble's redshift discovery, indicating the universe's expansion. The lesson concludes with a focus on wavefront diagrams to visualize these concepts.

What happens to the pitch of a sound as a siren approaches you?

Explain how the Doppler Effect can be observed in water waves.

What did Edwin Hubble discover about light in relation to the Doppler Effect?

Describe how the movement of the observer affects the frequency of waves.

How does the Doppler Effect apply to light moving away from an observer?
