Angle of Incidence To get the angle of incidence, first draw a normal NON’ perpendicular at the point O. Now, the angle of incidence may be defined as the angle between the incident ray and normal at the point of incidence. It is represented by letter ‘i’. Angle of...

The refraction of light may be defined as the phenomenon of change in direction of light, when it passes from one medium to another. The cause for refraction of light when it passes through one medium to another is the difference of velocity of light in different...

The linear magnification or magnification of a spherical mirror may be defined as the ratio of the size (height) of the image to the size (height) of the object. The magnification of a mirror is represented by the letter m. Thus m = Or m = where, h2 =...

A mirror formula may be defined as the formula which gives the relationship between the distance of image v, distance of object u, and the focal length of a mirror. It may be written as, where, v = Distance of image from pole of mirror u = Distance of object...

For measuring the various distances in the ray diagrams of reflection by spherical mirrors, we shall adopt the following system of signs called new cartesian sign conventions. All the distances in a ray diagram of reflection by spherical mirrors are measured from the...
