Across
- 4. A wave bouncing off a surface that it cannot pass through
- 8. Average distance between Earth and the Sun. We use this to measure distances within our solar system.
- 9. Transverse transfer of energy composed of photons. Matter is not required for the transfer of light waves.
- 11. When a wave bends as it changes speed. Speed changes from one medium to another
- 12. Longitudinal disturbance in matter that carry energy away from the source of noise
- 14. Apparent change in position of an object when you look at it from different places
- 15. Disturbances that transfer energy from place to place
- 16. A wave that causes the medium to vibrate at right angles (perpendicular) to the direction of the wave
- 17. Distance light travels in a year. We use this to measure distances outside of our solar system
Down
- 1. Two or more waves overlapping each other. This will result in either constructive or destructive interference.
- 2. Bending of a wave when it comes into contact with the edge of another object.
- 3. A wave in which the vibration of the medium is parallel to the direction the wave travels
- 5. Change in frequency and pitch of a sound that is caused by the movement of the source or listener.
- 6. Maximum displacement on a wave measured from its midline to the crest or midline to trough.
- 7. Disturbances in matter that carry energy from one place to another
- 10. Distance between corresponding points of two consecutive waves
- 13. The number of waves that pass over a fixed point in time.
