Flashcards in chapter 22 vocabulary Deck (16)
1

medium

physical environment in which phenomena occur

2

tranverse wave

a wave in which the particles of the medium move perpendicularly to the direction the wave is traveling

3

longitudinal wave

a wave in which the particles of the medium vibrate parallel to the direction of wave motion

4

amplitude

the maximum distance that the particles of a wave's medium vibrate from their rest position

5

wavelength

the distance from any point on a wave to an identical point on the next wave.

6

frequency

the number of waves produced in a given amount of time

7

wave speed

the speed at which a wave travels through a medium

8

crest

the highest point of a transverse wave

9

trough

the lowest point between each crest

10

compression

-a part of a longitudinal wave where the particles are crowded together

11

rarefaction

a part where the particles are spread apart

12

refraction

the bending of a wave as the wave passes between two substances in which the speed of the wave differs.

13

diffraction

a change in the direction of a wave when the wave finds an obstacle or an edge, such as an opening

14

interference

the combination of two or more waves that results in a single wave.

15

reflection

the bouncing back of a wave of light, sound, or heat when the wave hits a surface that it doesn't go through

16

wave

a periodic disturbance in a solid, liquid, or gas as energy is transmitted through a medium
