Question

Assertion : Magnification of real images is taken negative.

Reason : Magnification is ratio of image distance and object distance.​

Answer 1

Answer:

both assertion and reason are correct and reason is the correct explanation of assertion

Answer 2

Answer:

Both Assertion and Reason are correct and Reason is correct explanation of Assertion.

Explanation:

• Magnification is the ratio between the height of the object and the height of the image.

• The magnification produced by a lens is equal to the ratio of image distance to the object distance. Thus (m=v/u)
• In the case of a real image, the height of the object carries a positive sign while the height of the image carries a negative one.

Hence the magnification is Negative.
