Question

1. An object is placed at a distance of 20 cm in front of a convex mirror having focal 0.3 m. Find the position, nature and magnification of the image formed by the mirror




Please answer​

Answer 1

Explanation:

u=-20

f=+30cm

1/f=1/v+1/u

1/30=1/v+(-1/20)

1/30+1/20=1/v

v=6/5cm

m=-v/u

m=-6/5/-20

m=3/50cm

Answer 2

Answer:

THE IMAGE WILL BE UPRIGHT , VIRTUAL AND DIMINISHED.

Explanation:

in this case focal length = 30 cm and object distance = 20 cm

which means the object is between the pole and focus.
