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

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

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

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

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

None

The Law of Reflection states that the angle of incidence (i) is equal to the angle of reflection (r). How are these angles measured?

With respect to the incident ray.

With respect to the reflecting surface.

With respect to the direction of wave propagation.

With respect to the normal line.

None

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

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

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

both waves are traveling in the exact same direction.

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

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?

1.25 Hz

0.4 Hz

2.5 Hz

2.0 Hz

None

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

Resonance occurs in a system under forced oscillation when…

the driving frequency is much higher than the natural frequency

the amplitude of the oscillation is gradually decreasing to zer

the system is oscillating in a vacuum, preventing any damping.

the driving frequency matches the system’s natural frequency

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

parallel to the direction of energy transfer.

perpendicular to the direction of energy transfer

only when the wave passes from one medium to another

in circular paths, creating peaks and troughs.

None
