Waves, Light and Sound - Physics 101 / AP Physics 1 Review with Dianna Cowern

The video explores the nature of waves, using a slinky to demonstrate wave propagation. It distinguishes between longitudinal and transverse waves, explaining how sound and light travel. Key wave properties like frequency, wavelength, and amplitude are discussed, along with the wave equation. The video also covers the speed of sound and light, and how waves interact with matter, including refraction and the Doppler effect. The lesson concludes with a brief history of the universe's expansion and the concept of dark energy.
