Question

write the mirror formula
​

Answer 1

$\large{\frak{\red{Answer}}}$

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

Answer 2

Answer:

It is an equation relating object distance and image distance with focal length is known as a mirror equation. It is also known as a mirror formula.

Mirror Equation

In a spherical mirror:

• 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,

$\frac{1}{v} + \frac{1}{u} = \frac{1}{f}$

Where,

• u is the Object distance
• v is the Image distance
• f is the Focal Length given by f=R\ 2

• 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.
