- 17. Multiple Choice
What might explain why light travels in a straight line?
If there is nothing to interfere with light waves, they should travel in a straight line.
Light waves will always travel in a straight line, even if they come into contact with another object.
Light waves don't travel in a straight line.
Light waves travel in a straight line because sound waves travel in a straight line.
