Understanding Mechanical Waves

What is a key characteristic of mechanical waves?

• They can only travel through liquids.

• They are always visible.

• They require a medium to travel through.

• They can travel through a vacuum.

In a longitudinal wave, how does the disturbance move in relation to the wave's direction?

• Randomly

• Parallel

• Circular

• Perpendicular

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

• Light wave

• Sound wave

• Radio wave

• Water ripple

In a transverse wave, what is the relationship between the disturbance and the wave's direction?

• They move in opposite directions.

• They are perpendicular to each other.

• They are parallel to each other.

• They move in the same direction.

Which part of a transverse wave is the highest point?

• Compression

• Resting position

• Crest

• Trough
