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.
