Question

write rules for formation of image by spherical mirror​

Answer 1

Answer:

Explanation:General rules for image formation using ray diagrams:

Any ray of light that passes through the mirror, is always parallel to the principal axis.

Any ray of light that passes through the mirror always passes through the principal focus (f) of the mirror after reflection

Answer 2

Rules for Formation of Image by Spherical Mirrors

Rule 1 :- When a Ray of light parallel to principal Axis incident on a spherical mirror it always passes through focus for appear to come from focus.

Rule 2 :- When are a lot of light passes through focused and it becomes parallel to principal Axis after reflection from mirror.

Rule 3 :- When a Ray of Light passes through centre of curvature it retraces to some path after reflection .

Rule 4 :- When a Ray of light incidently falls on pole of mirror after reflection it follows up law of reflection that is angle of incidence is equal to angle of reflection.

Additional Information

Spherical Mirrors :- it is a part of a sphere which is published by point even inward side or outward side and one side acted as reflecting surface. There are two types of Spherical Mirror listed below:-

• Concave Mirror
• Convex Mirror

Concave Mirrors :- Those Mirrors in which the inward side of the sphere act as a reflecting surface and outward side is polished, such a mirror is called Concave mirror. it is also called converging mirror because it converges all the beam of light all on Focus in front of mirror. it generally forms real image.

Convex Mirrors :- Mirror in which bulging out light act as inward part or opaque or polished such a mirror is called Convex mirror. it is also called diverging mirror because the diverges all the parallel beam of life of reflection from mirror. But whenever it retraces back then it appears to come from principal focus.
