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.

According to the Law of reflection, a light ray striking a mirror

• continues moving through the mirror in the same direction
• moves into the mirror at a slightly different angle
• bounces off the mirror toward the direction it came from
• bounces off the mirror at the same angle it hits.
