Question 7

If we compare and contrast electromagnetic waves with sound waves, all BUT one statement is true. That is

Accepted Answer

electromagnetic waves must have a medium in which to travel, but sound waves can travel anywhere.

Answer

sound waves require a medium to travel while electromagnetic waves do not.

Answer

electromagnetic waves can travel through the vacuum of space while sound waves cannot.

Answer

sound waves must bounce off of matter in order to travel while electromagnetic waves do not require matter to be present.

Question 8

The distance from location C to location E, ________ to __________, equals one wavelength.

Accepted Answer

compression to compression

Answer

amplitude to amplitude

Answer

frequency to frequency

Answer

compression to rarefaction

Question 9

Sound waves are compression waves, as seen here. The areas of low pressure within a sound wave, area A for example, are called

Accepted Answer

rarefactions

Answer

amplitudes

Answer

frequencies

Answer

troughs

Question 10

Sound waves are longitudinal waves. The height or intensity of the wave shows its amplitude, or the energy in the wave. In the diagram of a sound wave, the section labeled B shows the area of the sound wave with the

Accepted Answer

most amplitude and compression.

Answer

most amplitude and rarefaction.

Answer

least amplitude and compression.

Answer

least amplitude and rarefaction.

Question 11

Sarah and Maria made a telephone using two cans and a string. It was a very long string. Maria went upstairs in her house and Sarah stayed downstairs. Maria spoke softly into the can. "I can hear you!' Sarah said back. How can this happen?

Accepted Answer

Sound waves travel through solids like the string.

Answer

Sound waves travel through a vacuum.

Answer

Sound waves travel from high to low.

Answer

Maria talked so loudly that Sarah could hear her without the phone.

Question 12

Maria talked so loudly that Sarah could hear her without the phone.

Accepted Answer

longer wavelength.

Answer

higher crest.

Answer

higher frequency.

Answer

greater amplitude.

Accepted Answer

C

Answer

A

Answer

B

Answer

D

Question 14

The wave pictured represents a sound wave. Which label along the wave represents a sound with the LOWEST intensity?

Accepted Answer

D

Answer

A

Answer

B

Answer

C

Question 15

Looking at waves A and B. Which description correctly describes the waves?

Accepted Answer

Wave B has twice the energy because it has an amplitude twice as large.

Answer

Wave A has twice the energy because it has a frequency twice as large.

Answer

Wave A has twice the energy because it has an amplitude twice as large.

Answer

Waves A and B gave the same energy because they have the same amplitude.

Question 16

The diagram shows a wave. The quantity shown is the amplitude. This quantity is directly proportional to which of these other quantities?

Accepted Answer

Energy

Answer

Frequency

Answer

Period

Answer

Wavelength

Question 17

The energy supplied to a speaker is increased. What will happen to the sound the speaker produces?

Accepted Answer

The sound will be louder or greater amplitude.

Answer

The sound will be lower pitch.

Answer

The sound will become a high pitched squeal.

Answer

The sound will remain unchanged if the speaker is not changed.

Question 18

If the above two waveforms were sound waves, we would hear the ___________ wave louder. If the above two waveforms were light waves, we would see the ________ wave dimmer.

Accepted Answer

green, red

Answer

red, red

Answer

red, green

Answer

green, green

Question 19

All of the waves in the electromagnetic spectrum are _______ waves.

Accepted Answer

transverse

Answer

compression

Answer

longitudinal

Answer

mechanical

Question 20

An old movie poster used a quote "In space, no one can hear you scream!" Why this is true or not true?

Accepted Answer

Sound needs a medium for the wave to vibrate and there is nothing in space to vibrate.

Answer

The quote is incorrect, you can hear sound in outer space.

Answer

Sound cannot be polarized. So, you cannot hear sound in space.

Answer

Sound is an electromagnetic wave and needs no medium to travel through.

Question 21

Which of these are not mechanical waves and can be used to send a signals to satellites orbiting the earth?

Accepted Answer

radio waves

Answer

sound waves

Answer

both sound waves and radio waves

Answer

neither sound waves or radio waves

Question 22

Sound waves are mechanical waves in which the particles in the medium vibrate in a direction parallel to the direction of energy transport. Identify another name for this type of wave motion.

Accepted Answer

longitudinal waves

Answer

transverse waves

Answer

pressure waves

Answer

electromagnetic waves

Question 23

What do we call the distance labeled from A to B and what could we do to the note played on an instrument to change that distance?

Accepted Answer

From A to B is known as the wavelength and changing the pitch of the note will change its length.

Answer

From A to B is known as the amplitude and changing the loudness of the note will change its length.

Answer

From A to B is known as the wavelength and changing the amplitude of the note will change its length.

Answer

From A to B is known as the wave height and changing the amplitude of the note will change its length.
