NCERT Solution for Class 10 Science Chapter 10 Light Reflection and Refraction
Define the principal focus of a concave mirror.
The principal focus of a concave mirror is a point on its principal axis to which all the light rays which are parallel and close to the axis, converge after reflection from the concave mirror.
Name a mirror that can give an erect and enlarged image of an object.
Why do we prefer a convex mirror as a rear-view mirror in vehicles ?
We prefer a convex mirror as a rear-view mirror in vehicles because of two reasons :
A convex mirror always produces an erect image of the objects.
The image formed in a convex mirror is highly diminished or much smaller than the object, due to which a convex mirror gives a wide field of view of the traffic behind. A convex mirror enables the driver to view such larger area of the traffic behind him.
