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 reflecting surface.

With respect to the direction of wave propagation.

With respect to the incident ray.

With respect to the normal line.

None

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

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

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.

None

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

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

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

Mechanical waves are always longitudinal, while electromagnetic waves are always transverse.

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

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?
