1.	A 3 times magnified image of both nature wasproduced by a concave mirror of focal length 12 cm.Determine the object and image distance from themissor for both real and image..
Answer» Answer: u= -8 cm & v=24 cm Explanation: -v/u=3 (given) or -v=3u or v=-3u f= -12 cm Putting the above values in the mirror formula: 1/v+1/u=1/f or 1/-3u + 1/u = 1/-12 or -1+3/3u = 1/-12 [TAKING 3u as LCM] or 2/3u=-1/12 or 3u = -24 or u=-24/3 or u= -8 cm We know, v=-3u Now v=-3-8 or v=24 cm*

Answer»

Answer:

u= -8 cm & v=24 cm

Explanation:

-v/u=3 (given)

or -v=3u

or v=-3u

f= -12 cm

Putting the above values in the mirror formula:

1/v+1/u=1/f

or 1/-3u + 1/u = 1/-12

or -1+3/3u = 1/-12 [TAKING 3u as LCM]

or 2/3u=-1/12

or 3u = -24

or u=-24/3

or u= -8 cm

We know, v=-3u

Now v=-3*-8

or v=24 cm
