Question

An object is placed at a distance of 10 cm from the pole of a convex mirror of focal length 15 cm. Find the nature and position of the object​

Answer 1

Given that:

⠀

⠀

u = – 10 cm

f = + 15 cm

⠀⠀

Where u means object distance and f means focal length of the convex mirror.

⠀⠀

To find:

⠀⠀

Nature and position of the object.

⠀⠀

Solution:

⠀⠀

⠀⠀

Now using mirror formula, we will find v.

⠀⠀⠀⠀

$\begin{gathered}\begin{gathered} \\ \\ : \implies \displaystyle \frac{1}{f} = \frac{1}{v} + \frac{1}{u} \\ \\ \end{gathered} \end{gathered}$

where f is focal length, u is object distance and v is image distance.

⠀⠀

Now we know that, magnification = image distance/object distance

⠀⠀

m = –v/u

⠀⠀

= –6/–10 = 0.6

⠀⠀

Since the magnification is positive and less than one, the image is erect and diminished and the positive sign indicates that the image is virtual.

⠀⠀

So, image formed is an erect, virtual and diminished image which is formed behind the mirror.

⠀⠀

Position of tme image is behind the mirror.
