Question

radius of curvature of a mirror is 24 cm name the kind of mirror and give the characteristics of image formed.

Answer 1

Answer:

Convex mirror

Explanation:

real and inverted as its positive number

Answer 2

Concept:

Spherical mirrors:  A spherical mirror is a part of a hollow sphere, whose one side is silvered or coated with red oxide and another side is a reflecting surface. The spherical mirrors are of two types -

a) Convex mirror

b) Concave mirror

Sign convention for measuring distances and length for spherical mirrors:

(i) The pole of the mirror is taken as the origin and the principal axis as X-axis. A line passing through the pole and perpendicular to the principle axis is taken as Y-axis.

(ii) All lengths and distances are measured from the pole as follows -

a) Distances measured along the principal axis to the right of the pole (+ X-axis) are taken as positive and those to the left of the pole (- X-axis) are taken as negative.

b) Distances measured upward (+ Y-axis) from the principal axis are taken as positive and the distances measured downward (- Y-axis) from the principal axis are taken as negative.

Answer:

The radius of curvature of a mirror = 24 cm or + 24 cm

We know that the radius of curvature of the convex mirror is positive because it lies on the right side of the pole.

Hence, the mirror is a convex mirror and a convex mirror always forms virtual, erect and diminished image.

Kind of mirror - Convex mirror

Nature of image formed - Virtual, erect and diminished
