when object
is in front of Concave mirror at a
disance 15 cm and focal length of
concave mirror is 10 cm
​

Answer 1

Step-by-step explanation:

Soln :-. Given u = -10cm , v= ? , f = -15cm

Applying mirror's formula,1/v +1/u = 1/f

1/v + 1/-10 = 1/-15

1/v = -1/15 + 1/10

=(-2+3)/30

= 1/30

V = 30 cm.

Hence, we get enlarged image, virtual in nature having magnification 3.
