Wave

Question 1

Medium

Answer 1

A medium is any substance that a wane moves through.

Question 2

Mechanical waves

Answer 2

Waves that transfers energy through matter are known as mechanical waves.

Question 3

Transverse wave

Answer 3

Transverse waves are the direction in which the wave travels is perpendicular or at right angles to the direction of the disturbance.

Question 4

Longitudinal wave

Answer 4

The travels in the same direction as the disturbance.

Question 5

Crest

Answer 5

A crest is the highest point or peak of a wave

Question 6

Trough

Answer 6

A trough is the lowest point or valley of the wave

Question 7

Amplitude

Answer 7

For a transverse wave is the distance between a line through the middle of the wave and a crest or trough

Question 8

Wavelength

Answer 8

The distance from one wave crest to the very next crest.

Question 9

Frequency

Answer 9

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

Question 10

Reflection

Answer 10

The bouncing back of a wave after it strikes a barrier

Question 11

Refraction

Answer 11

Is the blending of a wave as it enters a new medium at an angle other then 90 degrees

Question 12

Diffraction

Answer 12

Is the spreading out of waves through an opening of around the edge of an obstacle

Question 13

Interference

Answer 13

Is the meeting and combining of waves

Answer 22

Have frequencies from about 10.19 Hz to more then 10.24 Hz

Question 23

Wave

Answer 23

A wave is a disturbance that transfers energy from one place to another
