Define the Focal length of a spherical mirror
How is a spherical mirror used to diverge a beam of light from a point? Name the type of mirror used.
Which are the two convenient rays that are chosen to construct the image by a spherical mirror for a given object? Explain with the help of suitable ray diagrams.
A student obtained a sharp image of a burning candle, placed at the farther end of a laboratory table, on a screen using a concave mirror. For getting better value of focal length of the mirror, the subject teacher suggested him for focusing a well illuminated distant object. What should the student do?
(A) He should move the mirror away from the screen.
(B) He should move the mirror slightly towards the screen.
(C) He should move the mirror as well as the screen towards the newly selected object.
(D) He should move only the screen towards the newly selected object.
In each case (a) and (b), draw reflected rays for the given incident rays and mark focus by the symbol F.
The diagram below in Figure, shows a convex mirror. C is its centre of curvature and F is its focus. (i) Draw two rays from A and hence locate the position of image of object OA. Label the image IB. (ii) State three characteristics of the image.
Define the following term in relation to concave mirror.
Center of curvature
Define the following term in relation to concave mirror.
Focal length
Define the term Principle focus.
A concave mirror can be used to produce a parallel beam of light. Draw a ray to illustrate this.
