Define (a) centre of curvature (b) radius of curvature (c) pole (d) principal axis, and (e) aperture, of a spherical mirror with the help of a labelled diagram
When a spherical mirror is held towards the sun and its sharp image is formed on a piece of a carbon paper for some time, a hole is burnt in the carbon paper.
At which point of the spherical mirror the carbon paper is placed?
When a spherical mirror is held towards the sun and its sharp image is formed on a piece of a carbon paper for some time, a hole is burnt in the carbon paper.
What is the advantage of using a carbon paper rather than a white paper?
Define the terms focus and focal length of a concave mirror. Draw diagram to illustrate your answer.
For an incident ray directed towards centre of curvature of a spherical mirror the reflected ray:
Select the correct option:
A mirror forms a virtual image (diminished) of an object, whatever be the position of object:
What is the relation between focal length and radius of curvature of a concave mirror?
Complete the following diagrams shown in the following figures by drawing the reflected rays.
The diagram below shows the parallel rays incident on a convex mirror. C is the centre of the curvature of the mirror. By drawing the paths of the reflected rays, label the focus F and hence find the focal length of the mirror.
The distance from the center of curvature of the mirror to the pole is called the focal length of the mirror.
