Answer 2

Answer :-

• Image distance is 60/11 cm, image is formed on the right side of the mirror as v is negative and it is a virtual image.

Explanation :-

Given :

• Object distance (u) = -12 cm
• Radius of curvature (R) = 20 cm

To find :

• Image distance (v)

Solution :

Using the formula

• 1/u + 1/v = 2/R

Where,

• u = Object distance
• v = Image distance
• R = Radius of curvature

Substituting the values,

→ 1/v = 2/R - 1/u

→ 1/v = 2/20 - 1/-12

→ 1/v = 11/60

→ v = 60/11 cm

• Image is formed on the right side of the mirror as v is negative and it is a virtual image.
