Question

A concave mirror produces three times magnified (enlarged) real image of anobject placed at 10 cm in front of it. Where is the image located?
​

Answer 1

Answer:

Here Given Magnification:

m= -3 (real image)

The object distance :

u =-10cm

Now As we know,









Hence,

The image is at 30cm in front of the mirror.

Answer 2

Answer:

Image distance = 30cm

Explanation:

m = -3 ( -ve because it is real image)

u = -10cm

v=?

so,

m = - v/u

-3 = -(v/-10)

v/-10 = 3

v = -30
