A ship uses a SONAR system to measure the depth of the sea. It sends out an ultrasonic pulse and receives the echo 0.8 seconds later. If the speed of sound in seawater is 1500m s−1, what is the depth of the sea?

3000 m

1200 m

600 m

1875 m

None

A wave on a slinky spring has a wavelength of 0.6 m and a frequency of 5 Hz. What is the speed of the wave?

8.33ms−1

3.0ms−1

5.6ms−1

0.12ms−1

What is the primary characteristic that distinguishes a mechanical wave from an electromagnetic wave?

Mechanical waves transfer matter, while electromagnetic waves transfer only energy.

Mechanical waves require a medium for propagation, while electromagnetic waves do not.

Mechanical waves are always longitudinal, while electromagnetic waves are always transverse.

Mechanical waves travel at the speed of sound, while electromagnetic waves travel at the speed of light.

None

Wavelength

Speed

None

A simple pendulum completes one full oscillation (Y -> Z -> Y -> X -> Y). What is the total time taken for this motion called?

Frequency

Period

Wavelength

Amplitude

None

Which of the following correctly describes damping in an oscillating system?

Both the amplitude and the frequency of oscillation decrease over time.

An external force is continuously applied to keep the amplitude from decreasing.

The amplitude of oscillation decreases over time, but the frequency remains constant.

The frequency of oscillation decreases over time, but the amplitude remains constant.

None

Destructive interference occurs when two coherent waves meet at a point. This happens when…

the trough of one wave meets the trough of the other.

the crest of one wave meets the crest of the other.

both waves are traveling in the exact same direction.

the crest of one wave meets the trough of the other.

None

A sound wave is an example of a longitudinal wave. This means that the particles of the medium vibrate…

perpendicular to the direction of energy transfer

parallel to the direction of energy transfer.

only when the wave passes from one medium to another

in circular paths, creating peaks and troughs.

None

10.

A wave is generated in a ripple tank. If the frequency of the vibrator is increased while the depth of the water remains constant, what happens to the wavelength and the speed of the wave?

Wavelength remains constant, speed increases.

Wavelength decreases, speed remains constant.

Wavelength decreases, speed decreases.

Wavelength increases, speed increases

None
