  1. Wave Behavior Relfection, Refraction, Diffraction.

  2. Reflection • Reflection occurs when a wave strikes an object and bounces off of it. • All types of wavesincluding sound, water, and light wavescan be reflected

  3. Reflection When a wave bounces off a barrier or surface it is said to be reflected. How much of the wave that is reflected depends on the difference in the densities between the two mediums.

  4. Echo • Sometimes when the sound waves hit another object, they reflect off it and come back to you. • Your ears hear the sound again, a few seconds after you first heard your footstep. Reference echolocation

  5. Reflection • Reflection is when a wave encounters a new medium that acts as a barrier that does not absorb the entire wave’s energy. This causes the wave to return to the original medium. • All types of waves can be reflected.

  6. Types of Reflection

  7. Refraction • When a wave passes from one medium to anothersuch as when a light wave passes from air to waterit changes speed. • If the wave is traveling at an angle when it passes from one medium to another, it changes direction, or bends, as it changes speed.

  8. Refraction • Refraction is the bending of a wave caused by a change in its speed as it moves from one medium to another.

  9. Sound refraction • Sound wave will refract if there is a difference in air temperature. • The different densities cause the waves to bend.
