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

Wavelength

Direction

Speed

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

only when the wave passes from one medium to another

in circular paths, creating peaks and troughs.

parallel to the direction of energy transfer.

None

A displacement-time graph for a wave shows an amplitude of 5cm and a period of 0.4s. What is the frequency of the wave?

0.4 Hz

1.25 Hz

2.0 Hz

2.5 Hz

None

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

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.

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

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

None

The phenomenon of diffraction is most pronounced when…

the wavelength of the wave is much smaller than the size of the gap.

the amplitude of the wave is at its maximum.

the wavelength of the wave is approximately equal to the size of the gap.

the frequency of the wave is very high.

None

Which of the following phenomena does NOT change the frequency of a wave?

Reflection

None of these phenomena change the frequency.

Refraction

Diffraction

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?

1200 m

600 m

3000 m

1875 m

None

Microwaves

Gamma rays

Infrared

Ultraviolet

None

10.

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

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

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

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

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

None
