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 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.

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

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 increases, speed increases

Wavelength decreases, speed decreases.

Wavelength decreases, speed remains constant.

Wavelength remains constant, speed increases.

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 direction of wave propagation.

With respect to the incident ray.

With respect to the reflecting surface.

With respect to the normal line.

None

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

both waves are traveling in the exact same direction.

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

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

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

None

When water waves pass from a deep region to a shallow region, they undergo refraction. Which property of the waves remains unchanged?

Frequency

Direction

Speed

Wavelength

None

In the electromagnetic spectrum, which type of wave has a wavelength shorter than visible light but longer than X-rays?

Microwaves

Infrared

Ultraviolet

None

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

only when the wave passes from one medium to another

in circular paths, creating peaks and troughs.

perpendicular to the direction of energy transfer

parallel to the direction of energy transfer.

None

The phenomenon of diffraction is most pronounced when…

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

the amplitude of the wave is at its maximum.

the frequency of the wave is very high.

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