Transmission and absorption

• What is one way in which energy may be transferred between stores?

  Waves
• What do both mechanical and electromagnetic waves transfer?

  Energy
• What happens to matter when energy is transferred by waves?

  It does not move
• What occurs when waves arrive at the interface between two materials?

  • Waves can be reflected
  • Waves can be transmitted
  • Waves can be absorbed
• What is an example of a wave that can be transmitted through air, glass, and water?

  Light waves
• What happens when energy is absorbed by a material?

  The internal energy of the material increases
• What type of radiation from the Sun is absorbed by the surface of the Earth?

  Infrared radiation
• What factors determine what happens to most of the wave energy at an interface?

  The type of wave, its properties, and the difference between the two media
• How does wavelength affect wave energy at an interface?

  It affects how much energy is reflected, absorbed, or transmitted
