Waves

Question 1

A substance through which a wave moves.

Answer 1

Medium

Question 2

The breakdown of rock into smaller of the same material without any change in its composition.

Answer 2

Mechanical wave

Question 3

A type of wave in which the disturbance moves angels,or perpendicular, to the direction in which the wave travels.

Answer 3

Transverse wave

Question 4

A type of wave in which the disturbance moves in the same direction that the wave travels.

Answer 4

Longitudinal wave

Question 5

The highest point, or peak, of a wave.

Answer 5

Crest

Question 6

The lowest point, or valley, of the wave.

Answer 6

Trough

Question 7

The maximum distance that a disturbance causes a medium to move from its rest position; the distance between a crest or trough of a wave line though center of a wave.

Answer 7

Amplitude

Question 8

The distance from one wave peak or crest to the next peak or crest. Wavelength can be measured as the distance from any part of one wave to the identical part of the next wave.

Answer 8

Wavelength

Question 9

The number of waves the pass a fixed point in a given amount of time, usually on second; the number of cycles per unit time.

Answer 9

Frequency

Question 10

The bouncing back of a wave after it strikes a barrier

Answer 10

Reflection

Question 11

The bending of a wave as it crosses the boundary between two mediums at an angle other than 90 degrees

Answer 11

Refraction

Question 12

The meeting and combining of waves; the adding or subtracting of wave amplitudes that occurs as waves overlap.

Answer 12

Interference

Question 13

A disturbance that transfers energy from one place to another without requiring matters to move the entire distance.

Answer 13

Wave
