2. SPHERICAL MIRRORS
Spherical mirrors are mirrors whose reflective
surfaces form a hollow sphere.

3. The center of the circle that the
mirror is part of is point C.
C
The radius of the circle
that the mirror is part of is
distance R
R
Point C is called:
C= Center of Curvature
Distance R is called:
R= Radius of Curvature

4. SPHERICAL MIRRORS
TWO TYPES
 CONVEX MIRRORS
 CONCAVE MIRRORS

5. CONVEX MIRRORS
If the reflective surface of the mirror curved
outwards, it is said to be convex mirror.

6. CONCAVE MIRRORS
If the reflective surface of the mirror
curved inwards, it is said to be concave mirror.

8. FOCUS OF A CONCAVE MIRROR

9. FOCUS OF A CONVEX MIRROR

10. REAL AND VIRTUAL IMAGES
 In a concave mirror, the focus is real. The
object and the image lie on the same side
of the mirrored surface. It is captured on
a screen.
 In a convex mirror, the object and the
image lie on the opposite sides of the
mirrored surface. The image is a virtual
image. It cannot be captured on a screen.
