* mirror of focal length 6 cm. Find the location size and nature of the image​

Answer 1

Answer:

Image distance = 2.9 cm

size of image = 1.04 cm

nature of image = virtual, erect and magnified

Explanation:

ho = 3 cm

u = - 7.5 cm

f = 6 cm

1 /v + 1 /u = 1 /f

1 /v = 1 /6 - ( - 1 /7.5)

      = 40 /13.5

v = 2.9 cm

hi /ho = - v /u

hi = 1.04 cm

Image is virtual, erect and diminished.
