A new space film depicts an astronaut being startled by a nearby spaceship that blows up. In the film, the astronaut covers his ears during the explosion of the spaceship. What is wrong with these scene?
Sound requires a medium to travel; therefore, sound can't travel in space.

The top of a transverse wave is called the ....
Crest

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.
Sound and light travel through the vacuum of space, but sound waves are never able to reach Earth.
2! Sound waves are compressional waves and they cannot move through the vacuum of space.
