pathway
In the illustration, the light ray striking the object is-
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.
What is the angle of incidence?
The angle at which light bends in water.
The angle at which light hits a surface.
The angle at which light is absorbed by an object.
The angle at which light bounces off a surface.

56o
90o
124o
34o
