Physic Unit 6: Waves

3. the full range of electromagnetic radiation, organized by frequency or wavelength
5. the change in direction of a wave passing from one medium to another caused by its change in speed.
6. the highest point of a wave
7. refers to the perceptual quality of a sound that allows us to distinguish between high and low sounds
12. a wave that is an oscillation of matter.
13. a wave consisting of a periodic disturbance or vibration that takes place in the same direction as the advance of the wave.
14. abrupt change in the direction of propagation of a wave that strikes the boundary between different mediums.
15. which two coherent waves are combined by adding their intensities or displacements

1. refers to the number of waves that pass a fixed point in unit time
2. a type of wave that propagates along the boundary between two different media
4. the spreading of waves around obstacles.
8. the substance through which a wave or disturbance propagates
9. refers to the lowest point or dip in a wave
10. refers to the maximum displacement or distance a point on a vibrating body or wave moves from its equilibrium position
11. distance between corresponding points of two consecutive waves
