sound and light review

Astronauts in space cannot talk to each other unless they use a radio to speak back and forth. Why is this?

• The air is too thick to carry sound waves efficiently.

• The force of gravity is too strong to allow sound waves to travel.

• There is no air in space, so there is no medium to carry sound waves

• It is very loud in space, so they can only hear each other through a radio.
