Waves Quiz S3

What do waves transfer?

• Energy

• Matter

• Heat

• Light

What is a transverse wave?

• A wave that moves parallel to the direction of energy transfer

• A wave that moves perpendicular to the direction of energy transfer

• A wave that moves in a circular motion

• A wave that does not move

What is a longitudinal wave?

• A wave that moves parallel to the direction of energy transfer

• A wave that moves perpendicular to the direction of energy transfer

• A wave that moves in a circular motion

• A wave that does not move

Give an example of a transverse wave.

What is meant by the frequency of a wave?

• The number of waves passing a point per second

• The distance between two consecutive crests

• The height of the wave

• The speed of the wave

What is the period of a wave?

• The time taken for one complete wave to pass a point

• The distance between two consecutive crests

• The height of the wave

• The speed of the wave

What is diffraction?

• The bending of waves around obstacles

• The change in direction of waves when they pass from one medium to another

• The change in speed of a wave as it passes from one medium to another

• The reflection of waves off a surface
