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.
