Transverse and Longitudinal Waves

How do scientists primarily gain information about the Earth's deep interior?

• By analyzing rock samples from deep boreholes.

• By studying the behavior of seismic waves generated by earthquakes.

• By directly observing the Earth's core using specialized probes.

• By examining volcanic eruptions and magma composition.

What is the primary difference in particle motion between a longitudinal wave and a transverse wave?

• In a longitudinal wave, particle oscillation is parallel to wave propagation, whereas in a transverse wave, it is perpendicular.

• Longitudinal waves require a medium, while transverse waves do not.

• Transverse waves can be polarized, but longitudinal waves cannot.

• Longitudinal waves transfer matter, while transverse waves only transfer energy.

Which type of wave can travel through the vacuum of space without a medium?

• Mechanical waves

• Longitudinal waves

• Electromagnetic waves

• Sound waves

What characteristic allows transverse waves, such as light, to be polarized?

• Their ability to transfer energy through a vacuum.

• Their capacity to oscillate in multiple planes perpendicular to the direction of propagation.

• The oscillation of particles parallel to the direction of wave propagation.

• Their dependence on a physical medium for transmission.
