Question 11

What is being transferred during the movement of a wave?

Answer 11

energy

Question 12

Light wave changes direction due to

Answer 12

refraction

Question 13

Why does the light wave change direction?

Answer 13

The object stops the light wave from continuing change of speed.

Question 14

Describe the relationship[ between amplitude and energy.

Answer 14

The larger the amplitude of the wave the more energy.

Describe the relationship between frequency and wavelength.

Answer 15

If a wave is longer they have a lower frequency. Wave is shorter, frequency is higher.

Only electromagnetic waves can move through

Answer 16

empty space/vacuum

Question 17

In a transverse wave, a measure of the distance from one trough to the next is the wave’s

Answer 17

wavelength

In a _____ wave, particles move parallel to the direction in which the wave travels.

Answer 18

longitudinal

Question 19

In a _____ wave, the disturbance is perpendicular to the direction in which the wave travels,

Answer 19

transverse

Question 20

The distance from one crest to the next crest is a wave’s

Answer 20

wavelength

Question 21

The Sun’s energy can mover through space because it travels as

Answer 21

electromagnetic waves

Question 22

The frequency of a wave is the

Answer 22

number of wavelength that pass by a point each second

Question 23

A longitudinal wave makes particles in a medium

Answer 23

move back and forth parallel to wave movement

Question 24

Describe the relationship between amplitude and compressions in a sound wave:

Answer 24

Compression is measured in wave lengths from each one. Amplitude is measured from rest or medium to crest or trough

Question 25

Describe the relationship between amplitude and crests in a transverse wave.

Answer 25

The amplitude goes from rest to crest, you need a crest or trough to get the amplitude

Question 26

Answer 33

the number of wavelengths pass by a point each second

Question 34

Answer 34

Sound waves in air travel faster on a warm day than o cold winder day. Inc. Temp Inc. Speed.

Question 35

How does the type of matter affect the speed a sound wave travels?

Answer 35

What is loudness and how is it determined?

Answer 37

the human sensation on how much energy a sound wave carries

Question 38

What is the relationship between amplitude and loudness?

Answer 38
