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

Frequency

Direction

Wavelength

Speed

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 crest of the other.

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

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

None

A wave on a slinky spring has a wavelength of 0.6 m and a frequency of 5 Hz. What is the speed of the wave?

5.6ms−1

0.12ms−1

3.0ms−1

8.33ms−1

None

The phenomenon of diffraction is most pronounced when…

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

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

the amplitude of the wave is at its maximum.

the frequency of the wave is very high.

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?

Reflection

None of these phenomena change the frequency.

Diffraction

Refraction

None

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 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.

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

None

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

in circular paths, creating peaks and troughs.

parallel to the direction of energy transfer.

only when the wave passes from one medium to another

perpendicular to the direction of energy transfer

None

10.

With respect to the normal line.

With respect to the reflecting surface.

With respect to the direction of wave propagation.

With respect to the incident ray.

None
