Explain the following term related to spherical lenses:- optical centre
A virtual image larger than the object can be produced by a ______.
Name the spherical mirror which can produce a virtual and diminished image of an object.
A ray of light travels from a denser medium to a rarer medium. How will it bend?
Name the kind of mirror used to obtain:
A virtual and enlarged image
Define the following term:
convex mirror
The following Figure shows a concave mirror MM' on which a ray of light incident from a point P gets reflected to meet the principle axis at O.
(a) Find, by construction, the position of the centre of curvature of the concave mirror.
(b) Write down the value for the radius of curvature of the mirror.
(c) Calculate the focal length of the mirror.
(d ) Which relation is used in deducing the focal length from the radius of curvature?
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.
If the focal length of a spherical mirror is 10 cm, what is the value of its radius of curvature?
