Nature of Waves Quiz

What is a wave?

• A transfer of particles from one place to another

• A transfer of energy without transferring matter.

• A transfer of heat through vibrations.

• A disturbance that only occurs in solids.

Which of the following is an example of a transverse wave?

• Sound wave

• Water wave

• Ultrasound

• Earthquake (p-wave)

In a longitudinal wave, the particles of the medium move:

• Perpendicular to the direction of the wave

• Along the direction of the wave

• In circular motions

• In no specific direction

The distance between two successive crests of a wave is called:

• Amplitude

• Wavelength

• Frequency

• Wave speed

If the frequency of a wave is doubled while the speed remains the same, what happens to the wavelength?

• It doubles

• It halves

• It stays the same

• It quadruples

The speed of a wave is 300m/s, and its frequency is 50Hz. What is the wavelength?

• 6m

• 50m

• 150m

• 600m

What is the unit of frequency?

• Metre (m)

• Hertz (Hz)

• Joules (J)

• Second (s)

When a wave reflects off a surface, the angle of incidence is:

• Greater than the angle of reflection

• Less than the angle of reflection

• Equal to the angle of reflection

• Unrelated to the angle of reflection

Which of these best describe refraction:

• The bending of waves as they enter a different medium

• The spreading out of waves through an opening

• The bouncing back of waves

• The overlapping of waves to form interference

Sound waves cannot travel through:

• Solids

• Liquids

• Gases

• A vacuum
