24 Quiz II

What is the primary characteristic that distinguishes surface waves on a body of water from other types of waves?

• They travel through the air.

• They involve the movement of water particles in circular paths.

• They require a solid medium to propagate.

• They do not transfer energy.

Explain how energy is transferred in surface waves on a body of water.

• Energy is transferred through the compression of water particles.

• Energy is transferred by the vertical displacement of water particles.

• Energy is transferred through the circular motion of water particles.

• Energy is transferred by the horizontal movement of water particles.

In the context of wave propagation in ropes, what is the primary factor that affects wave speed?

• The color of the rope.

• The tension in the rope.

• The length of the rope.

• The temperature of the surrounding air.

Describe the process of energy transfer in a wave traveling through a rope.

• Energy is transferred by the compression of rope fibers.

• Energy is transferred through the oscillation of rope particles perpendicular to the direction of wave travel.

• Energy is transferred by the rotation of rope fibers.

• Energy is transferred through the longitudinal movement of rope particles.

How does the speed of a wave in a rope change if the tension in the rope is increased?

• The speed decreases.

• The speed remains the same.

• The speed increases.

• The speed becomes zero.

Calculate the speed of a wave in a rope with a tension of 100 N and a mass per unit length of 0.5 kg/m.

• 10 m/s

• 20 m/s

• 14.14 m/s

• 40 m/s

What is the relationship between wave speed, frequency, and wavelength in any medium?

• Wave speed = Frequency + Wavelength

• Wave speed = Frequency - Wavelength

• Wave speed = Frequency / Wavelength

If the frequency of a wave in a rope is doubled, what happens to the wavelength, assuming the wave speed remains constant?

• The wavelength doubles.

• The wavelength remains the same.

• The wavelength is halved.

• The wavelength becomes zero.

Discuss the effect of medium density on the speed of surface waves on water.

• Higher density increases wave speed.

• Higher density decreases wave speed.

• Density has no effect on wave speed.

• Higher density makes wave speed infinite.

What happens to the energy of a wave as it propagates through a medium?

• It is completely absorbed by the medium.

• It is transferred to the medium without any loss.

• It is gradually dissipated as heat.

• It remains constant throughout the medium.
