Question

A candle is placed 12 cm from a concave mirror of focal length 12 cm as shown. Where is the location of the image?

Answer 1

Explanation:

according to mirror formula

1/u+1/v=1/f

u=-12cm

v=?

focal length =12

therefore,

1/-12 +1/v = 1/12

1/v = 1/12+1/12

1/v =1/6

hence 6cm is your answer
