Question

what is the nature of image formed by a concave mirror if the magnification produced by the mirror is + 3​

Answer 1

Answer:

Virtual, erect and magnified

Explanation:

The magnitude of the magnification is greater than 1, so the image is magnified.

The magnification is positive, so the image is erect.

For a real object, an erect image produced is always virtual.

Hence the image is virtual, erect and magnified.

what is the nature of image formed by a concave mirror if the magnification produced by the mirror is + 3

ANSWER ⤵️

• if magnification is positive then image will be erect and virtual.

more information

• lens formula= 1/f = 1/v+ 1/u
• mirror formula= 1/f = 1/v - 1/u
• if object is takes as negative,it means that it is placed on the left side of the mirror.
• if object is taken as positive it means that object is placed on right side of the mirror.
• convex lens and mirror always have a positive focal length.
• concave lens and mirror always have negative focal length.

v = image distance

u= object distance

f= focal length
