Wavelength

Question 12

This sound has high pitch, which means it has a higher frequency. This means when you hear the sound...

Accepted Answer

More waves hit your ears per second

Answer

Bigger waves hit your ears

Answer

Less waves hit your ears per second

Answer

Longer waves hit your ears

Question 13

All waves carry energy from one place to another, but some waves carry more energy than others. A leaf falling on water produces waves so small they are hard to see. An earthquake under the ocean can produce huge waves that cause great destruction.

What affects the energy of a wave? Select the 3 that apply.

Accepted Answer

The energy in a wave is determined by amplitude, which is the distance from the rest position of a wave to the top or bottom.

Accepted Answer

Large amplitude waves contain more energy.

Accepted Answer

The energy in a wave is determined by frequency, which is the number of waves that pass by each second.

Answer

The medium (material) moving along with the wave.

Question 14

A disturbance that transfers energy from place to place through matter or space

Accepted Answer

wave

Answer

position

Answer

time

Answer

protein

Question 15

Frequency and period are closely related. Frequency is the inverse of period.

suppose the time from one crest to another (one crest to another is also known as "the period") is 5 seconds; what is the frequency?

Select the 2 that apply.

Accepted Answer

.2

Accepted Answer

1/5

Answer

.5

Answer

1/2

Question 16

One hertz is equal to:

Accepted Answer

1 cycle per second

Answer

1 amplitude

Answer

1 frequency

Answer

all the cycles in the wavelength

Question 17

The particles in cold air have less kinetic energy than the particles in warm air. this means that they collide less often and take longer to transmit a sound wave pulse. What is this an explanation of:

Accepted Answer

the speed of sound

Accepted Answer

the speed of mechanical energy

Answer

the speed of electromagnetic energy

Answer

the speed within a vacuum

Question 18

Each wavefront expands in a sphere, spreading the energy across a larger area. This means that the energy per unit area of the wave decreases as it moves farther form its source, causing the loudness of the sound wave to decrease. This is an example of:

Accepted Answer

energy of the sound wave changing as it moves farther away from the source.

Answer

energy of the sound wave remaining constant as it moves farther away from the source.

Answer

energy of the sound wave increases as it moves farther away from the source.

Question 19

How are Electromagnetic waves different from Mechanical waves?

Accepted Answer

EM waves can travel through the vacuum of space (without particles)

Answer

EM waves have very short wavelengths

Answer

EM waves transmit energy instead of matter

Answer

EM waves can change direction by reflection

Question 20

Wavelength and Frequency are related in that...

Accepted Answer

when one increases, the other decreases (inversely proportional)

Answer

they are always the same

Answer

there is no correlation

Answer

they both vary in an irregular pattern
