Longitudinal wave

The video explains that longitudinal waves propagate in the same direction as the medium they travel through. Sound waves are a prime example, as they move air particles back and forth in the direction of the wave. These waves are also known as compression waves.

What is the direction of movement of the medium in longitudinal waves?

• Opposite to the wave direction

• In the same direction as the wave

• In a circular motion

• Perpendicular to the wave direction

Which of the following is an example of a longitudinal wave?

• Sound waves

• Light waves

• Radio waves

• Water waves

How do particles in the air move when a sound wave travels through it?

• Up and down

• Back and forth in the same direction as the wave

• In a spiral motion

• In a random pattern

What is another name for longitudinal waves?

• Shear waves

• Transverse waves

• Surface waves

• Compression waves

Which term is used to describe the movement of particles in a longitudinal wave?

• Compression

• Oscillation

• Rotation

• Vibration
