It travels in a straight line without stopping.
It comes to a stop after it travels a certain distance.
It changes direction often even if there are no objects.
- 15. Multiple Choice
Communication in space occurs by using radio waves because
space does not have waves
space is too big for sound to travel and light reflects more easily
sound needs a medium (like air) to be carried and space has not medium (it's a vacuum)
