Question

OH
A 5 cm tall object is placed at a distance of 30 cm from a convex mirror of focal length 15
cm. Find the position, size and nature of the image formed. Also draw the ray diagram​

Answer 1

Answer:

position = 30 cm left from pole

size = -5 cm

nature = ∵ m is -ve inverted and real image is formed

Explanation:

f = -15 cm

u = -30 cm

1/f = 1/v + 1/u

from above equation v = - 30

m = - v / u ⇒ m = -1

hi/ho = -v/u ⇒ hi = -5
