Light and Waves: Understanding Properties and Interactions

Explore the properties of light waves and how they interact with different mediums. Learn why black spots on a cat's fur appear black and how light passes through air, water, glass, and vacuum at varying speeds. Understand wave interactions like reflection and refraction. Discover the science behind why the color orange appears as it does.

  2. The spots on a cat appear black because… A. The black fur absorbs all light B. The black fur reflects all light C. The black fur diffracts all light D. The black fur refracts all light 2/18/14 Rank the following based on how quickly light can pass through each one: air, water, glass, vacuum 1st Fastest: 2nd: 3rd: 4th slowest:

  3. Rank the following based on how quickly sound can pass through each one: air, water, glass, vacuum 1st Fastest: 2nd: 3rd: Cannot travel: 2/20/14 • The picture above illustrates which wave interaction? • Reflection b. Refraction • c. Absorption d. Diffraction

  4. Which property of light waves explains why the pencil appears broken? • Light is reflected • Light is absorbed • Light is diffracted • Light is refracted 2/20/14 The color orange that we see depends upon the… • speed of the orangelight wave • wavelength of the orange light wave • temperature of the orange light wave • direction of the orange light wave
