Waves and Sound

What is a wave?

• A - An irregular transfer of energy
• B - An irregular transfer of matter
• C - A regular pattern of motion that transfers energy
• D - A regular pattern of motion that transfers matter

In what ways can you observe a wave?

• A - You can see waves
• B - You can feel waves
• C - You can hear waves
• D - All of the above

What is a medium?

• A - A substance through which a wave travels
• B - Another term for equilibrium
• C - The highest or lowest point on a wave
• D - A regular and repeating vibration

Where is the rest position on the wave below?

• A
• B
• C
• D

What is a mechanical wave?

• A - A wave that transfers matter
• B - A wave produced by magnets or electricity
• C - A wave produced by a moving or vibrating object
• D - A type of light wave

Which statement correctly describes a mechanical wave?

• A - A mechanical wave requires a medium to travel through.
• B - A mechanical wave can travel through a vacuum.
• C - Light is a type of mechanical wave.
• D - A mechanical wave transfers matter.

As a transverse wave moves across a medium (left or right), particles in the medium will:

• A - move up only
• B - move down only
• C - move up and down
• D - move left and right

As a longitudinal wave moves across a medium (left or right), particles in the medium will:

• A - move up only
• B - move down only
• C - move up and down
• D - move left and right

How do particles of a medium move as a surface wave passes through it?

• A - Parallel to the motion of the wave
• B - Perpendicular to the motion of the wave
• C - In a circular motion
• D - Particles do not move in the medium

What is amplitude?

• A - The height of a wave
• B - The length of one complete wave
• C - The time it takes to complete one wave
• D - The number of times a wave cycles in one second
