What is the difference between mechanical waves and electromagnetic waves?

• Mechanical waves require a medium to travel. Electromagnetic waves can travel through matter or space.

• There is no difference, they are the same thing.

• Mechanical waves DO NOT require a medium to travel. Electromagnetic waves MUST HAVE a medium in order to travel.

What are the TWO types of mechanical waves?

• Transverse waves

• Longitudinal waves

• Electromagnetic waves

• Radio waves

What direction does the medium travel in relation to the direction of the wave in transverse waves?

• The medium travels perpendicular (or at right angles) in relation to the direction of the wave.

• The medium travels in the same direction (parallel) as the direction of the wave.

What are compressional (or longitudinal waves)? Select all that apply.

• Waves that require a medium to travel.

• Waves in which the medium moves back and forth in the same direction (parallel) to the direction of the waves.

• Waves that can travel through mediums AND space.

• Waves that can travel through space ONLY.

Seismic waves and water waves are a combination of transverse waves and longitudinal waves. True or false?

• True

• False
