Waves And Energy 1.1

Question 1

Any substance that has a wave move through.

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 highest point or peak of a wave

Answer 5

Crest

Question 6

The lowest point or valley of a 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 and line through the center of a wave

Answer 7

Amplitude

Question 8

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

Answer 8

Wave length

Question 9

The number of waves passing a fixed point in a certain amount of time

Answer 9

Frequency

Question 10

The bouncing back of a wave after it strikes 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°

Answer 11

Refraction

Question 12

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

Answer 12

Diffraction

Question 13

The meeting and combing of waves; the adding of subtracting of wave amplitudes that occurs as waves overlap

Answer 13

Interference

Question 14

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

Answer 14

Wave
