science

1. he phenomenon that occurs when two waves meet while traveling along the same medium.
3. change in direction of propagation of any wave as a result of its traveling at different speeds at different points along the wave front.
5. a disturbance in a medium that carries energy without a net movement of particles
6. build up features on the surface of the Earth.
7. a decrease in the density of something.
9. wave vibrating in the direction of propagation.
10. a wave vibrating at right angles to the direction of its propagation.
11. a long depression less steep than a trench.
12. The process by which one substance, such as a solid or liquid, takes up another substance, such as a liquid or gas, through minute pores or spaces
13. A pressing or squeezing together.
14. abrupt change in the direction of propagation of a wave that strikes the boundary between different mediums.
15. A passage or transfer, as of a disease from one individual to another or of neutral impulses from one neuron to another
16. the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position

1. Pertaining to, governed by, or in accordance with, mechanics, or the laws of motion
2. the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
4. science of charge and of the forces and fields associated with charge.
6. The highest surface part of a wave
8. occurs when waves come together so that they completely cancel each other out.
17. the spreading of waves around obstacles.
