Question

the concave mirror produces of magnification -1 the object placed
plz ans​

Answer 1

Answer:

when object is placed at C

Explanation:

given m=-1

⇒ $-\frac{v}{u} = -1$     (using magnification formula i.e m=$- \frac{v}{u}$

⇒ $\frac{v}{u} = 1$         (Cancelling '-' on both sides)

⇒ v=u

i.e object distance = image distance

which is possible only  when object is placed at C i.e at 2f distance.

i.e object distance = 2f

and image distance = 2f

Answer 2

Explanation:

Means the object object is opposite and image is real
