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 increases, speed increases

Wavelength decreases, speed decreases.

Wavelength decreases, speed remains constant.

None

When water waves pass from a deep region to a shallow region, they undergo refraction. Which property of the waves remains unchanged?

Wavelength

Direction

Frequency

Speed

None

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

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

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

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

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?

600 m

1875 m

1200 m

3000 m

None

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

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

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