Sound/Mechanical Waves

Which type of wave has a wave perpedicular to the disturbance?

• surface
• mechanical
• transverse
• longitudinal

What happens when a mechanical wave travels through a medium?

• Waves are transferred
• Energy is transferred
• Mass is transferred
• Particles are transferred

Which of these waves cannot travel in a vacuum?

• light wave
• sound wave
• electromagnetic wave
• microwave

What is the wavelength of a wave?

• the size of the disturbance
• the amount of time that occurs in one full cycle
• the distance between two crests of a wave
• the amount of cycles that occur in a given time

A transverse wave can be created in a Slinky^® by moving it

• side to side.
• in a circular motion.
• together and apart.
• up and down.

When on a flat surface, giving the Slinky^® a push or pulse will create a disturbance

• in the opposite direction of the wave motion.
• parallel to the wave motion.
• in a circle.
• perpendicular to the wave motion.

What is the speed of a wave if the wavelength is 100 m and the period is 20 s?

• 2,000 m/s
• 120 m/s
• 80 m/s
• 5 m/s

An echo is an example of what type of property of waves?

• Reflection

• Diffraction

• Pitch

• Resonance

Pitch of a sound wave is the way we perceive...

Sound waves are also known as ----- waves.

• Compression

• Longitudinal

• Neither

• Both longitudinal and compression
