Class 10 Chapter 10 Light Reflection And Refraction

1) Define The Principal Focus of Concave Mirror?

2) The radius of curvature of spherical mirror is 20 cm what is its focal length?

3) Name of mirror that can give an erect and enlarged image of object?

4)Why do we prefer a convex mirror as rear view mirror in vehicle?

1) A number of ray parallel to the principal axis of the mirror they meet at a point on the principle excess of mirror this point is called principle focus of Concave mirror

2) Radius Of Curvature =20cm

Focal length = R/2 =10 cm

3) Concave mirror can give an erect and enlarged image of the object

4)We use a convex mirror as rear view mirror in vehicles as it gives an wider view of the road
