A concave mirror always forms a real image.
What do you understand by the focus and focal length of a spherical mirror? Show them on the separate diagrams for each of a concave mirror and a convex mirror.
Three mirrors are created from a single sphere. Which of the following - pole, centre of curvature, radius of curvature, principal axis - will be common to them and which will not be common?
Write two more characteristics of the image.
Name the kind of mirror used to obtain :
A real and enlarged image
Define the following term in relation to concave mirror.
Center of curvature
Does the mirror name by your form a real image for all locations? Give a reason for your answer.
Numerical problem.
The radius of curvature of a spherical mirror is 25 cm. Find its focal length.
Assertion: Incident ray is directed towards the centre of curvature of spherical mirror. After reflection it retraces its path.
Reason: Angle of incidence (i) = Angle of reflection (r) = 0°
