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 normal line.

With respect to the reflecting surface.

With respect to the direction of wave propagation.

With respect to the incident ray.

None

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

Speed

Direction

Wavelength

Frequency

None

Resonance occurs in a system under forced oscillation when…

the system is oscillating in a vacuum, preventing any damping.

the driving frequency matches the system’s natural frequency

the amplitude of the oscillation is gradually decreasing to zer

the driving frequency is much higher than the natural frequency

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 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.

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

None

A ship uses a SONAR system to measure the depth of the sea. It sends out an ultrasonic pulse and receives the echo 0.8 seconds later. If the speed of sound in seawater is 1500m s−1, what is the depth of the sea?

1875 m

3000 m

1200 m

600 m

None

The phenomenon of diffraction is most pronounced when…

the frequency of the wave is very high.

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

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

the amplitude of the wave is at its maximum.

None

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

perpendicular to the direction of energy transfer

in circular paths, creating peaks and troughs.

parallel to the direction of energy transfer.

only when the wave passes from one medium to another

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 remains constant.

Wavelength decreases, speed decreases.

Wavelength remains constant, speed increases.

Wavelength increases, speed increases

None
