The Mysteries of Life With Tim & Moby: Refraction and Diffraction

概要

Refraction and diffraction sure sound the same, so why are they so different? In this BrainPOP movie, Tim and Moby teach you the similarities and differences between the two processes. For instance, you’ll see why both are properties of waves! You’ll learn about light waves and photons, and how they can bend when moving through different materials. Find out how the speed of light can change when moving through objects with different densities, like air, water, or glass. And discover how light, sound, and radio waves can bend or spread around an obstacle, plus how scientists use diffraction to study everything from DNA to stars in outer space! We’re talking about the wave of the future, here!
