Webof curvature of the mirror. It is represented by the letter R. You may note that the distance PC is equal to the radius of curvature. Imagine a straight line passing through the pole and the centre of curvature of a spherical mirror. This line is called the principal axis. Remember that principal axis is normal to the mirror at its pole. WebThe effect of curvature being greater than that of refraction, the combined effect causes the points to appear to be lower than they actually are.
