5. (a) Define principal focus of a spherical mirror
(b) For what position of the object does a concave mirror form a real
inverted and diminished image of the object? Draw the ray diagram
@
(c) An object 4 cm high is placed at a distance of 6 cm in front of a
concave mirror of focal length 12 cm. Find the position of the image!
Answers
- The principal focuse of a concave mirror is a point on its principal axis to which all the light rays r parallel and close to the axis, converge after reflecting from the concave mirror.
