Waves Quiz

Which statement best defines mechanical waves based on what they travel through?

• Waves that require a medium (matter like air, water, or solids) to travel

• Waves that only travel through a vacuum (empty space)

• Waves that can travel without a medium and move at the speed of sound

• Waves that exist only as light and radio signals

According to the study guide, which key characteristic applies to electromagnetic (EM) waves?

• Cannot travel through a vacuum and only move through solids

• Can travel through a vacuum and through matter; all EM waves travel at the speed of light

• Move slower than mechanical waves in all materials

• Require a medium such as air or water to travel

Which example is correctly matched to its wave category?

• Sound waves are electromagnetic waves

• Water waves are mechanical waves

• X-rays are mechanical waves

• Microwaves are mechanical waves

A longitudinal (compression) wave is defined by how its particles move. Which description matches the definition?

• Particles vibrate perpendicular to the direction the energy travels

• Particles vibrate in random directions, independent of energy flow

• Particles vibrate parallel to (in the same direction as) the energy flow

• Particles remain stationary while energy moves past

Identify the compression (high-density) area of this longitudinal wave.

Which statement correctly describes compression in a longitudinal wave?

• A region where particles are spread apart, resulting in low density

• The area where particles are crowded together (high density) and is the highest energy point

• A region of zero motion where energy is absent

• The point where the wavelength is shortest but density is lowest

Identify the rarefaction (low-density) area of this longitudinal wave.

Rarefaction in a longitudinal wave is best described as which of the following?

• The high-density region where particles bunch together

• The low-density region where particles are spread apart

• A boundary where mechanical waves become electromagnetic waves

• A point with the highest amplitude in transverse motion

Which statement compares mechanical and electromagnetic waves accurately?

• Both require a medium to travel and cannot move through a vacuum

• Only mechanical waves travel at the speed of light

• Mechanical waves require a medium; EM waves do not and can travel through a vacuum

• EM waves require liquids or solids, while mechanical waves travel through empty space

Which of the following is an example of a longitudinal wave? (select all that apply

• Light waves

• Radio waves

• Sound waves

• Microwaves
