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

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

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

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

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

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 decreases, speed decreases.

Wavelength increases, speed increases

Wavelength decreases, speed remains constant.

Wavelength remains constant, speed increases.

None

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

Refraction

Reflection

Diffraction

None of these phenomena change the frequency.
