Which of the following is a type of mechanical wave?

• Electromagnetic wave

• Sound wave

• Light wave

• Gamma ray

What is the main difference between transverse and longitudinal waves?

• Transverse waves require a medium, while longitudinal waves do not.

• Transverse waves have oscillations perpendicular to the direction of wave travel, while longitudinal waves have oscillations parallel to the direction of wave travel.

• Transverse waves travel faster than longitudinal waves.

• Longitudinal waves can only travel through solids.

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

• Water wave

• Light wave

• Sound wave

• Radio wave

• Frequency

• Amplitude

• Wavelength

• Wave speed

Which property of a wave is defined as the maximum displacement of points on a wave from the rest position?

• Wavelength

• Frequency

• Amplitude

• Speed

What is constructive interference?

• When two waves meet and cancel each other out.

• When two waves meet and their amplitudes add together.

• When a wave reflects off a surface.

• When a wave changes direction as it passes from one medium to another.

What is the result of destructive interference?

• Increased amplitude

• Decreased amplitude

• No change in amplitude

• Doubling of frequency

What happens to a wave when it passes from a less dense medium to a more dense medium?

• It speeds up

• It slows down

• It maintains the same speed

• It disappears

Which of the following is true about the refraction of waves?

• It only occurs with sound waves.

• It involves a change in wave speed and direction.

• It only occurs when waves hit a boundary at a 90-degree angle.

• It results in the wave being absorbed.

What is Snell's Law?
