Object 20 CM in from of convex mirror image formed 15 CM behind the mirror find the focus
Answers
Answer:
u=−20 (a) v=−15
f 1 = v 1 + u 1
f 1 =− 15
1 − 20
1 f=− 7 60 cm
Focus is negative so mirror will be Concave mirror
(b) v=+15
Using the same formula:
f 1 = 15
1 − 20
1 f=60cm
Focus is positive, So mirror will be Convex mirror
