A model camera contains a thin converging lens. A ray of light from an object travels at an angle to the principal axis and passes through the optical centre of the lens.
Which describes the path of the ray after it has passed through the lens?
it leaves travelling along the principal axis
it continues along the same straight line
its angle to the principal axis becomes smaller
it is refracted so that it leaves parallel to the principal axis
