Unit 11 Energy Quiz

What is the difference between mechanical waves and electromagnetic waves?

• Mechanical waves do not need a medium to travel through as electromagnetic waves do
• Mechanical waves need a medium to travel through as electromagnetic waves don't
• Mechanical waves are transverse waves and electromagnetic waves are longitudinal
• There is no difference between the two types of waves

Frequency is measured in what?

• seconds
• meters
• hertz
• meters/second

What is a wave?

• An irregular transfer of energy

• An irregular transfer of matter

• A regular pattern of motion that transfers energy

• A regular pattern of motion that transfers matter

What is a medium?

• A substance through which a wave travels

• Another term for equilibrium

• The highest or lowest point on a wave

• A regular and repeating vibration

What is an oscillation?

• A substance through which a wave travels

• Another term for equilibrium

• The highest or lowest point on a wave

• A regular and repeating vibration

Which statement correctly describes a mechanical wave?

• A mechanical wave requires a medium to travel through.

• A mechanical wave can travel through a vacuum.

• Light is a type of mechanical wave.

• A mechanical wave transfers matter.

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

• move up only

• move down only

• move up and down

• 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

What is a surface wave?

• A - A wave that travels along the surface of a medium
• B - A wave that travels along the bottom of a medium
• C - A type of transverse wave
• D - A type of longitudinal wave

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
