Question

Help me out with this question. Want a proper answer.​

Answer 1

Object Distance(u) = 10 cm. (negative)

Focal length of the lens (f) = 5 cm.

We know, convex mirror always forms the virtual, upright and diminished.Also, Object distance in the convex mirror is always negative where as Image distance and focal length are positive.

Now, Applying the Mirror's Formula,

f

1

=

v

1

+

u

1

=

5

1

=

v

1

+

1

=

5

1

=

10v

(10−v)

10v=50−5v

15v=50

v=

3

10

so the image distance (v) =3.33cm.
