Waves

Question 1

What is a WAVE?

Answer 1

A disturbance that transfers energy from place to place.

Question 2

What is a MECHANICAL WAVE?

Answer 2

A wave that transfers energy through matter.

Question 3

What is an ELECTROMAGNETIC WAVE?

Answer 3

A wave that transfers energy through empty space.

Question 4

What is a MEDIUM?

Answer 4

Material (Matter) through which mechanical waves can travel.

Question 5

In what direction does a wave move relative to its source (the point of the disturbance)?

Answer 5

It moves in the opposite direction of its source (away/outward from the source)

Question 6

When a wave travels through a medium, only _________________ moves from place to place, not the particles of the medium.

Answer 6

Energy

Question 7

What happens to water particles as a wave moves through the water?

Answer 7

They do not move forward with the wave. They move in circular motions.

Question 8

Water waves carry __________________.

Answer 8

Energy

Question 9

Water is a _______________ for waves.

Answer 9

Medium

Question 10

Particles move in ___________________ as wave energy movies forward.

Answer 10

Circles

Question 11

Some waves, such as ______________ waves, DO NOT REQUIRE A MEDIUM.

Answer 11

Electromagnetic

Question 12

Light waves can travel through ______________________.

Answer 12

Empty space.

Question 13

When a wave moves through a medium, only ___________________ moves from place to place.

Answer 13

Energy

Question 14

What is a transverse wave?

Answer 14

a wave in which the particles of the medium move up and down at right angles to the direction of wave motion (the direction the energy travels).

Question 15

What is the crest of a wave?

Answer 15

It is the high point of a transverse wave.

Question 16

What is the trough (troff) of a wave?

Answer 16

It is the low point of a transverse wave.

Question 17

What is a longitudinal wave?

Answer 17

a wave in which the particles of the medium move back and forth in the direction of the wave motion.

Question 18

What is compression in a longitudinal wave?

Answer 18

part of a medium where the particles are pushed close together

Question 19

What is rarefaction in a longitudinal wave?

Answer 19

part of a medium where the particles are far apart.

Question 20

What are the two types of mechanical waves?

Answer 20

Transverse (like ocean) and Longitudinal (like sound)

Question 21

What is the difference between transverse and longitudinal waves?

Answer 21

The difference is in the movement of particles in the medium.

Question 22

How do particles move in a transverse wave?

Answer 22

The particles move at right angles (perpendicular) to the direction the energy is traveling through the medium.

Question 23

How do particles move in a longitudinal wave?

Answer 23

The particles stretch and compress in the same direction as the direction the energy is traveling through the medium.

Question 24

What are the two parts of a transverse wave?

Answer 24

Crest (high point) and Trough (low point)

Question 25

What is the medium for sound?

Answer 25

Air is the medium

Question 26

What are the two parts of a longitudinal wave?

Answer 26

Compression (particles close together) and Rarefaction (particles are far apart).

Question 27

All waves carry ____________.

Answer 27

Energy

Question 28

The difference between the longitudinal and transverse waves depends on how the ________________ of the medium move.

Answer 28

Particles

Question 29

The particles of the medium move up and down in a __________________ wave.

Answer 29

Transverse

Question 30

The particles of the medium move back and forth in a ___________________ wave.

Answer 30

Longitudinal

Question 31

The parts of the transverse wave are the crest and the ________________.

Answer 31

Trough

Question 32

Clapping your hands produces which type of wave?

Answer 32

Longitudinal (sound)
