Transverse and Longitudinal Waves

The two types of mechanical waves are

• transverse and longitudinal

• transverse and lateral

• traditional and longitudinal

In longitudinal waves, the particles travel __________ to the direction of the wave.

• parallel (same direction)

• perpendicular (right angle)

The tightly squeezed together parts of a longitudinal wave are called_____________, and the stretched out parts of a longitudinal wave are called_____________.

• Squeezes, Stretches

• Compressions, Rarefactions

• Pushes, Pulls

• Rarefactions, Compressions

Describe the motion of particles in a longitudinal wave?

• They displace by vibrating up and down until they reach the eardrum.

• They vibrate perpendicular to the direction of motion of the wave from one particle to the next.

• They displace by vibrating from one particle to the next along the direction of motion of the wave.

Sound is a type of

• Longitudinal wave

• Transverse Wave

• pulse, up and down

• up and down, pulse
