Question

An object is kept on the principal axis of a concave mirror of focal length
12 cm. If the object is at a distance of 18 cm from the mirror, calculate the
image distance. Determine the nature of the image formed by calculating
the magnification produced by the mirror​

Answer 1

Answer:

Step-by-step explanation:

1/f=1/u+1/v

1/v=1/f-1/u       for any  concave lens focal length is negative

1/v=-1/12- 1/18

1/v=-30/216=-5/36

v=-36/5

magnification=-v/u

m=-(-36/5)/18

m=2/5=0.4

so the nature of the image is REAL AND MAGNIFIED
