Wave motion

What is wave motion?

• The movement of particles in a straight line.
• The disturbance that propagates and transfers energy.
• The oscillation of water in a pond.
• The process of sound traveling through air.

What is the primary characteristic of mechanical waves?

• They travel at the speed of light.
• They can travel through a vacuum.
• They require a medium to propagate.
• They are always sound waves.

Which of the following best describes the difference between mechanical and electromagnetic waves?

• Mechanical waves are faster than electromagnetic waves.
• Mechanical waves require a medium, while electromagnetic waves do not.
• Mechanical waves can travel through a vacuum, while electromagnetic waves cannot.
• Mechanical waves are only sound waves, while electromagnetic waves are only light waves.

In a transverse wave, what are the highest points called?

• Crests
• Troughs
• Compressions
• Rarefactions

Which of the following statements about longitudinal waves is true?

• They are always sound waves.
• They require a medium to travel.
• They can travel through a vacuum.
• Particles vibrate perpendicular to the wave direction.

If a wave has a high frequency, what can you infer about its wavelength?

• The wavelength is long.
• The wavelength is constant.
• The wavelength is short.
• The wavelength is irrelevant.

What is wave frequency?

• The number of waves produced in one second.
• The maximum displacement of particles.
• The distance between two waves.
• The speed at which waves travel.

What is the relationship between wavelength and wave type?

• Wavelength is the same for both transverse and longitudinal waves.
• Longitudinal waves have wavelengths defined by their amplitude.
• Transverse waves have wavelengths measured between crests or troughs.
• Transverse waves have longer wavelengths than longitudinal waves.

How can Jacuzzi tubes be used in physiotherapy?

• They create sound waves for healing.
• They are used to measure wave frequency.
• They generate electromagnetic waves for therapy.
• They use circular waves of water for treatment.
