Answer 5

False

Question 6

What happens to a duck on the surface of a pond when a wave passes under it, Explain?

Answer 6

The duck stays in them same spot. Waves travel transfer energy, not matter.

Answer 9

Transverse waves

Question 10

Suppose you move the free end of a rope up and down to create a wave. In that case, the rope is a medium. What is the relationship between the movement of the wave and the movement of the particles of the medium

Answer 10

The particles are moving perpendicular to the wave’s motion

Answer 14

Compression

Question 15

In longitudinal waves a spring, the parts where the coils are spread out are called

Answer 15

Rarefaction

Question 16

The maximum distance the particles of the medium carrying a wave move away from their rest position is called the wave’s

Answer 16

Question 17

The amplitude of a wave is a direct measure of the wave’s

Answer 17

energy

Question 18

The distance between two corresponding parts of a wave is its

Answer 18

wavelength

Question 19

The number of complete waves that pass a given point in a certain amount of time is called the wave’s

Answer 19

Answer 23

Reflection

Question 24

Give an example of reflection

Answer 24

Mirror/glass

Question 25

Only transverse waves obey the law of reflection, True or False

Answer 25

False

Question 26

What happens when a wave moves from one medium to another medium at an angle, (must refer to speed)

Answer 26

The wave may speed up or slow down. When entering a second medium causing it to bend

Question 27

The bending of waves as they enter a different medium is called

Answer 27

Refraction

Question 28

All waves change speed when they enter a new medium, but they do not always bend. When does bending occur

Answer 28

When one side of the wave enters the new medium before the other side of the wave

Question 29

The bending of a wave entering a new medium occurs because the two sides of the wave are traveling at different

Answer 29

Speeds

Diffraction

Question 32

When two waves meet, they have an effect of each other. This interaction is called

Answer 32

Interference

Question 33

When does constructive interference occure

Answer 33

A crest interferes with another crest producing a larger amplitude

Question 34

When the amplitudes of two waves combine with each other to produce a smaller amplitude is called

Answer 34

Destructive

Question 35

What is a standing wave

Answer 35

Two waves of identical frequency interfere with one another while traveling in opposite directions along the same medium
