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

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

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

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

Resonance occurs in a system under forced oscillation when…

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

the amplitude of the oscillation is gradually decreasing to zer

the driving frequency is much higher than the natural frequency

the driving frequency matches the system’s natural frequency

None

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

None of these phenomena change the frequency.

Refraction

Diffraction

Reflection

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 are always longitudinal, while electromagnetic waves are always transverse.

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

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

None
