Module 1 Lesson 1 Final Assessment

What is a wave?

• Any disturbance that transmits energy through matter or empty space

• A solid object that moves in water

• A type of animal

• A type of plant

Do waves transmit matter?

• Yes

• No

What is a medium in the context of waves?

• A type of wave

• A substance through which a wave can travel, such as water or the ground

• The highest point of a wave

• The lowest point of a wave

Electromagnetic waves do not need a _______ in which to travel.

• medium

• battery

• wire

• circuit

What is the highest point of a transverse wave called?

• crest

• trough

• node

• amplitude

What is the lowest point of a transverse wave called?

• trough

• crest

• node

• amplitude

The difference between a transverse wave and a longitudinal wave is based on the direction in which particles travel. Which statement is correct?

• In a transverse wave, particles move perpendicular to the direction of wave travel, while in a longitudinal wave, particles move parallel to the direction of wave travel.

• In a transverse wave, particles move parallel to the direction of wave travel, while in a longitudinal wave, particles move perpendicular to the direction of wave travel.

• Both types of waves have particles moving in the same direction as the wave.

• Particles do not move in either type of wave.

Which part of a transverse wave is called the crest and which part is called the trough?

• Crest is the highest point, trough is the lowest point

• Crest is the lowest point, trough is the highest point

• Both crest and trough are the same point

• Crest and trough are not parts of a transverse wave

The part of a longitudinal wave where the particles are more tightly-packed is called a _________

• compression

• rarefaction

• amplitude

• wavelength

The part of a longitudinal wave where the particles are more spread apart is called a _________.

• rarefaction

• compression

• node

• crest
