Light introduction

If an opaque object on the path of light becomes very small, light has a tendency to

bend around it and not walk in a straight line

• Scattering

A spherical mirror, whose reflecting surface is curved inwards, that is, faces towards the centre of the sphere, is called

• Concave mirror

• Convex mirror

• Half is concave and half is convex mirror

• Always Convex mirror

The centre of the reflecting surface of a spherical

mirror is a point called

The diameter of the reflecting

surface of spherical mirror is called

• Focal length

• Radius of Curvature

• Aperture

• Pole

Identify the surface
