**Lenses Physics Ppt**. A ray passing through the center of any lens continues in a straight line. An image formed by a convex lens is described by the lens equation 1 u + 1 v = 1 f where uis the distance of the object from the lens;

The refraction at the first surface is balanced by the refraction at the second surface. Other sign conventions are sometimes used in the literature.

The principle behind the lens is the refraction of light. An application of refraction there are 2 basic types of lenses a converging lens (convex).

• an optical system (mirrors or lenses) can produce an image of the object by redirecting the light. Other sign conventions are sometimes used in the literature.

The principle behind the lens is the refraction of light. Each of a lens’ two faces is part of a sphere and can be convex or concave if a lens is thicker at the center than the edges. it is a convex. or converging. lens since parallel rays will be converged to meet at the focus. The lens is transparent piece of glass or plastic which has a curved surface.

#### There Are Two Types Of Lenses:

Parallel to the axis refracts through f ray #2: N 1 n 2 n =1 1 bending angle depends on value of n 2 n 1 focal point focal length. f note: They are convex and concave lenses.

#### Powerpoint Can Be Used To Help In The Teaching Of Refraction. Lenses And Magnification.

Spherical lenses are of two main types. The thin lens equation can be applied to several lenses in sequence. always setting the image of the previous lens to be the object of the next. Lens continues in a straight line.

#### With A Concave Mirror. The Image May Be Either Real Or Virtual.

Physics teacher who is rich in years and who likes writing and sharing resources. An image formed by a convex lens is described by the lens equation 1 u + 1 v = 1 f where uis the distance of the object from the lens; The object in this case is beyond the focal point. and. as usual. the place where the refracted rays appear to diverge from is the location of the image.
