Lenses. Physics 202 Professor Lee Carkner Lecture 23. Refraction. Mirrors can be used to magnify an object or to gather light Lenses can be used for the same purposes Lenses gather light and magnify objects through refraction instead of reflection

Lenses. Type of lenses: Convex lens Convave lens. Refraction Rules for 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 focus on the opposite side of the lens.

Lenses

Lenses. Lenses use the process of refraction to change the direction of light at their two surfaces. There are two types of lenses: 1. CONVERGING - These make a parallel beam of light converge to a focus.

Lenses

Lenses. As light enters into a new medium it may bend due to refraction. So on a flat piece of glass all light rays remain parallel. Snells Law states that the ratio of the sin of the angle of incidence to the sin of the angle of refraction is a constant for each material. Lenses.

LENSES

LENSES. A light ray bends as it enters glass and bends again as it leaves This refraction is due to the difference in the average speed of light in glass and in air. Glass of a certain shape can form an image that appears larger, smaller, closer, or farther than the object is actually viewed.

Lenses. Knowing how curved mirrors reflect light can help you understand how lenses affect light rays. A lens is a curved piece of transparent material. Light refracts as it passes through a lens, causing the light rays to bend . Basic Lens Shapes.

Lenses. Refraction of Light. When light travels through a surface between two different media, the light will be refracted if the angle of incidence is greater than zero. If light is passing into a more dense media, it will bend towards the normal. www.hyperphysics.phy-astr.gsu.edu.

LENSES

LENSES. A lens is defined as - A ground or molded piece of glass, plastic, or other transparent material with opposite surfaces either or both of which are curved, by means of which light rays are refracted so that they converge or diverge to form an image. LENSES.

LENSES. Lyzinski Physics. Light Speeds. When traveling through a vacuum, light travels at 3 x 10 8 m/s. This is the fastest light ever travels. We shall refer to this as the SPEED OF LIGHT. When traveling through a different “medium” (substance), light slows down .
