Question

state mirror formula​

Answer 1

Answer:

Explanation:

The distance between the object and the pole of the mirror is called the object distance(u).

The distance between the image and the pole of the mirror is called Image distance(v).

The distance between the Principal focus and pole of the mirror is called Focal Length(f).

In ray optics, The object distance, image distance, and Focal length are related as,

1v+1u=1f

Where,

u is the Object distance

v is the Image distance

f is the Focal Length given by f=R2

R is the radius of curvature of the spherical mirror

The above formula is valid under all situations for all types of spherical mirrors (Concave and Convex) and for all object positions.

Answer 2

see answer

Explanation:

Let's explore the mirror formula (1/f = 1/v+1/u) and see how to locate images without drawing any ray diagrams.
