Waves

Question 1

A substance through which a wave moves.

Answer 1

Medium

Question 2

A wave such as a sound wave or seismic wave that transfers kinetic energy through matter.

Answer 2

Mechanical wave

Question 3

A type of wave in which the disturbance moves at right angles 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 bouncing back of a wave after it strikes a barrier.

Answer 5

Reflection

Question 6

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

Answer 6

Refraction

Question 7

The spreading out of waves as they pass through an opening or around the edges of an obstacle.

Answer 7

Diffraction

Question 8

The meeting and combining of waves.

Answer 8

Interference

Question 9

The highest point or peak of a wave.

Answer 9

Crest

Question 10

The lowest point or valley of a wave.

Answer 10

Trough

Question 11

The maximum distance that a disturbance causes a medium to move from its rest position.

Answer 11

Amplitude

Question 12

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

Answer 12

Wavelength

Question 13

The number of waves that pass a fixed point in a given amount of time usually one second.

Answer 13

Frequency

Question 14

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

Answer 14

Wave
