Question

an object of height 4 centimetre is placed at a distance of 12cm in front of a concave mirror of focal length 24 cm find the nature and size of the image​

Answer 1

h=4cm

u=-12cm

f=-24cm

1/v+1/u=1/f (MIRROR FORMULA)

1/v=1/f-1/u

1/v=-1/24+1/12(SIDE CHANGE AND SIGN CHANGE)

1/v=lcm =48

now,

1/v=-2+4/48

1/v=2/48

1/v=1/24

V = -24
