Which of the following phenomena does NOT change the frequency of a wave?

Diffraction

Reflection

Refraction

None of these phenomena change the frequency.

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

the frequency of the wave is very high.

None

A simple pendulum completes one full oscillation (Y -> Z -> Y -> X -> Y). What is the total time taken for this motion called?

Frequency

Period

Amplitude

Wavelength

None

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

Resonance occurs in a system under forced oscillation when…

the driving frequency is much higher than the natural frequency

the amplitude of the oscillation is gradually decreasing to zer

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

the driving frequency matches the system’s natural frequency

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?

3000 m

600 m

1875 m

None

10.

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.

only when the wave passes from one medium to another

perpendicular to the direction of energy transfer

parallel to the direction of energy transfer.

None
