Unit 1 - Lesson 2 - Term 2Waves and Sound Quiz

Transverse wave consists of

• compressions and rarefactions.

• troughs and rarefactions.

• compressions and crests.

• crests and troughs.

The longitudinal wave consists of

• compressions and rarefactions.

• troughs and rarefactions.

• compressions and crests.

• crests and troughs.

In the opposite figure, the particles of the medium (the coil) vibrate

• to the right only.

• upwards only.

• to the right and left.

• upwards and downwards.

Water waves are transverse waves because the particles of the medium

• vibrate perpendicular to the direction of wave propagation.

• do not vibrate.

• don't need a medium to propagate through.

• vibrate along the direction of wave propagation.

All of the following are transverse waves, except... waves

• water

• light

• sound

• radio

The electric bell produces pulses of

• compressions and rarefactions.

• crests and troughs.

• crests and rarefactions.

• compressions and troughs.

Scientists saw the explosions that occur on the Sun surface, but they couldn't record the sound...

• doesn't travel from up to down.

• needs a medium to travel through.

• is mechanical waves that propagate in a definite direction.

• is electromagnetic waves that don't propagate through free space.

Sound waves are longitudinal waves because the particles of the medium...

• don't need a medium to propagate through.

• don't vibrate.

• vibrate along the direction of wave propagation.

• vibrate in a direction perpendicular to the direction of wave propagation.

The highest point of the particles of the medium in the transverse wave is known as the...

• crest.

• compression.

• rarefaction.

• trough.

Rarefaction is the area at which the medium particles...

• don't vibrate.

• are too close to each other.

• are far away from each other.

• vibrate up and down.
