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

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.

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

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.

in circular paths, creating peaks and troughs.

only when the wave passes from one medium to another

perpendicular to the direction of energy transfer

None

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

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

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.

None

The phenomenon of diffraction is most pronounced when…

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

the frequency of the wave is very high.

the amplitude of the wave is at its maximum.

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

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 remains constant, speed increases.

Wavelength increases, speed increases

Wavelength decreases, speed remains constant.

None
