Waves Quiz and Test

Question 1

What do waves carry?

Answer 1

Energy

Question 2

What are the properties of waves?

Answer 2

Speed, amplitude, frequency, and wavelength

Question 3

How do you calculate the speed of a wave?

Answer 3

speed= wavelength x frequency

Question 4

How do you perceive color?

Answer 4

We use our primary colors which mix, then reflect a certain color back to our eyes.

Question 5

5. Differentiate between a transverse wave and a longitudinal wave. Be sure to describe the motion of each wave, and tell the direction the particles travel in each.

Answer 5

A longitudinal wave is a wave in which the disturbance of space of matter moves in a direction that is in the same direction as the transfer of energy. It includes compression, amplitude, refractions, and wavelength. A transverse wave is a wave in which the disturbance of space or matter moves in a direction that is perpendicular to the direction of the transfer of energy. A transverse wave includes a crest, wavelength, amplitude, and trough.

Question 6

Mechanical wave

Answer 6

a mechanical wave is the sum of a potential and kinetic energy in a system of interacting objects.

Question 7

Electromagnetic wave

Answer 7

a wave of energy propagated in an electromagnetic field

Question 8

Frequency

Answer 8

for a wave, the number of crest passing a given point per unit time

Question 9

Amplitude

Answer 9

• the distance from the midpoint of a wave to the crest (or trough) of the wave

Question 10

Wavelength

Answer 10

the distance from one wave crest to the next (or the distance from one trough to the next)

Question 11

Speed

Answer 11

rate at which someone or something moves or operates

Question 12

transparent

Answer 12

lets visible light pass through

Question 13

translucent

Answer 13

materials that let light pass through, but isn’t see through

Question 14

opaque

Answer 14

materials that don’t let light pass through at all

Question 15

Compare sound waves and light waves.

Answer 15

Sound waves require a medium to travel and travels through vibration. A longitudinal wave. A light wave is a transverse wave.

Question 16

How does amplitude affect the pitch of sound?

Answer 16

If the amplitude increases, the pitch increases.

Question 17

As the energy increases, the frequency _________.

Answer 17

increases

Question 18

crest

Answer 18

the highest point of a wave

Question 19

trough

Answer 19

the lowest point in a wave

Question 20

compression

Answer 20

an area in a longitudinal wave where the particles of a medium are closest together

Question 21

rarefaction

Answer 21

an area in a longitudinal wave where the particles are farthest apart

Question 22

Increase amplitude -> decrease _________ -> increase in ___________.

Answer 22

wavelength, frequency

mechanical waves require a _________-and are classified by ______________.

Answer 23

medium, how they move.

Question 24

frequency affects the _________.

Answer 24

pitch

Question 25

amplitude affects ______________.

Answer 25

sound

Question 26

rarefaction

Answer 26
