Question

a light ray parllel to the principal axis reflected from the mirror.draw the reflected ray and show the direction​

Answer 1

Explanation:

the light from the sun is converged at a point,as a sharp,bring spot by the mirror.In fact,this spot of light is the image of the sun on the sheet of paper.this point is the focus of the concave mirror,

The heat produced due to the concentration of sunlight ignites the mirror gives the approximate value of focal length of the mirror.

A number of ray parallel to the principal axis are falling on a concave mirror.observe the reflected ray, they are all melting / intersecting at a point on the principle axis of the mirror.this point is called the principal axis of the mirror.

this point is called the principal focus of the concave mirror.

The reflected ray appears to come from a point on the principle axis. the point is called the principal focus of the convex mirror.the principal focus is represent by the letter F. the distance between the pole and the principal focus of a spherical mirror is called the focal length.it is represent by a letter from.

the reflecting surface of a spherical mirror is by and large spherical.the surface,then,has a circular outline.the diameter of the reflecting surface of spherical mirror is called it's aperture.

MN represent the apartur......
