Waves

Although light is visible from stars, we cannot hear the sound created from the explosions on those stars. Light is a transverse wave and sound waves are compressional waves.

Which statement is correct about light and sound waves?

• Light waves are transverse waves and they cannot move through the vacuum of space.

• Sound waves are compressional waves and they cannot move through the vacuum of space.

• Light waves and sound waves have identical properties, regardless of whether they are compressional or transverse waves.
