9.  Mechanical waves can be ______or ______.

10.  Electromagnetic waves are ______.

11.  Compressional waves or ______waves look like a Slinky. They look like they bunch up then spread out as they travel. This is because they travel parallel to the force. Matter particles move ______. ______waves are Compressional.

Behaviors of Waves

1. Refraction is the ______caused by a change in their speed as they pass from ______to another. As waves pass at an angle from one medium to another, they may ______. The greater the change of speed of the waves, the more ______.

2. Refraction of light going from air through a ______can make images appear larger as the light ______.

3.______separate white light into its different components or colors by bending light at different angles depending on the different frequencies. Different colors of light have ______.

4. Reflection is the ______of a wave when it meets a surface or boundary that does not absorb the entire wave's energy. All ______can be reflected.

5. Reflections of sound waves are called ______can help bats and dolphins learn about their environments.

6.______and other ______reflect light to form clear images.

7. ______of waves occurs when waves pass through a given point or medium.

8. Sound waves are transmitted through ______.

9. Light waves are transmitted through …

·  ______materials (this can be clear or colored materials) that allows ______to pass through. Only a small amount of light is reflected or absorbed.

·  ______materials allow ______waves to be transmitted through them.

·  ______materials transmit some light but cause it to be scattered so no ______

______can be seen.

10. Absorption of certain frequencies of light occurs when the energy is not ______through or ______by the given medium.
