What do waves transmit through matter or space?

• Sound only

• Light only

• Energy

• Heat only

How do the vibrations in a transverse wave relate to the direction of wave propagation?

• The vibrations are in the same direction as the wave propagation.

• The vibrations are at right angles to the direction of wave propagation.

• The vibrations are in a circular motion around the direction of wave propagation.

• There are no vibrations in a transverse wave.
