Question

acquire the skill of draw ray diagrams of spherical mirrors?

Answer 1

Spherical Mirror

Explanation:

• Spherical mirror is two types

1. concave mirror
2. convex mirror

• In a concave mirror reflection of light takes  place takes place in the bent in surface or concave surface.
• In a convex mirror reflection of light takes place at  the building-out surface or convex surface.
• The focal point of a spherical mirror is defined by what the mirror does to a set of rays of light that are parallel to one another and to the principal axis of the mirror .
• A concave mirror is contrast , reflects parallel rays so that they diverge away from the focal point.
• The fact that spherical mirrors do not really bring all such rays to a point (or diverge them away from a point) is a defect called spherical aberration.

For a concave mirror: f=+R/2.

For a convex mirror:f=-R/2.
