A lens is a curved piece of glass or plastic that redirects beams of light bouncing off of an object to form a real image - an image that looks just like the object in front of the lens.
A lens is a curved piece of glass or plastic that redirects beams of light bouncing off of an object to form a real image - an image that looks just like the object in front of the lens.
As a ray of light enters a lens, it is refracted twice - when it enters the lens and when it exits it. The light ray changes directions at these two boundaries. The light rays are refracted such that they form images.
Converging Lens
Converging Lens
A ray traveling through the exact center of the lens will continue to travel in the same direction after refracting through the lens.
Refraction by a Converging Lens
Refraction by a Converging Lens
Rays traveling parallel to the principal axis will refract through the lens and converge to a point
