Question

The magnification produced by a lens is $m=-1.5$. What are the characteristics of the image formed?

• A. Real, inverted and diminished
• B. Virtual, erect and magnified
• C. Real, inverted and magnified
• D. Virtual, erect and diminished

Answer 1

The correct option is C Real, inverted and magnified

Magnification produced by the lens is given by:
$m=\frac{v}{u}=-1.5$

The numerical value of magnification is greater than 1 indicating that the image formed is bigger than the object, i.e., enlarged.
The negative sign signifies that the image is inverted with respect to the object. A lens forms an inverted image, only if it is real.

So, the image is real, enlarged and inverted.
