Across
- 4. is defined as the process of repeating variations of any quantity or measure about its equilibrium value in time
- 8. the number of waves that pass a fixed point in unit time; also, the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.
- 9. periodic back-and-forth motion of the particles of an elastic body or medium
- 11. is a branch of Physics, that deals with the electromagnetic force that occurs between electrically charged particles.
- 13. abrupt change in the direction of propagation of a wave that strikes the boundary between different mediums.
- 14. the change in direction of a wave passing from one medium to another caused by its change in speed.
- 15. decrease in volume of any object or substance resulting from applied stress.
Down
- 1. the physical properties and phenomena of something.
- 2. the point on the medium that exhibits the maximum amount of positive or upward displacement from the rest position.
- 3. a wave or signal whose frequency is an integral (whole number) multiple of the frequency of the same reference signal or wave.
- 5. measure of the bending of a ray of light when passing from one medium into another
- 6. a substance or material that carries the wave.
- 7. the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
- 10. the point on the medium that exhibits the maximum amount of positive or upward displacement from the rest position.
- 12. segment of one cycle of a longitudinal wave during its travel or motion, the other segment being compressed
