Which type of waves require a medium to travel through?

• Electromagnetic waves

• Radio waves

• Gravity waves

• Mechanical waves

Answer explanation

Mechanical waves require a medium to travel through. They cannot propagate in a vacuum or empty space.

Which of the following is not an example of a mechanical wave?

• Electromagnetic wave

• Seismic wave

  (Earthquakes)

• Water wave

• Sound wave

Answer explanation

An electromagnetic wave is not an example of a mechanical wave because it does not require a medium to propagate. Mechanical waves, such as seismic waves, water waves, and sound waves, require a medium to travel through.

Which of the following is not an example of a compressional (also called longitudinal) wave?

• Seismic wave

• Slinky

• Ocean wave

• Sound wave

Answer explanation

An ocean wave is not an example of a compressional wave because it is a transverse wave.

Which type of wave vibrates in the direction of its motion?

• Transverse waves

• Longitudinal or Compressional waves
