Parallel to the principal axis
Most of the time, a light ray passing through the atmosphere in any direction curves away from its original direction toward the earth's surface. Occasionally, light can proceed straight through the atmosphere with no change in direction. Rarely, it can bend away from the surface.
becomes more converging
The road through the tires of the car. It is caused by the new bias of the tires allowing the car to proceed only in the assigned direction.
Light can not change direction by passing from one kind of mater to another. In fact, light can only pass through its own type of matter, which is when things like light can go through each other (and only a few types of matter can do that), but even in that case since it can go through, it can't be bent in angle by passing through.

REFLECTION
A converging lens changes the direction of light through the process of refraction. A lens is a device that uses refraction to bend light to form an image.
A converging lens is thin at the ends and thick in the middle. It is called converging because the rays of light passing through it, if parallel, converge at a point the other side. A magnifying glass uses a converging lens.

Any incident ray traveling parallel to the principal axis of a converging lens will refract through the lens and travel through the focal point on the opposite side of the lens.Any incident ray traveling through the focal point on the way to the lens will refract through the lens and travel parallel to the principal axis.An incident ray that passes through the center of the lens will in effect continue in the same direction that it had when it entered the lens.
