Question

For the real and enlarged image ,magnificationcan be(a) -1(b)1.98(c)-; (d) - 0.98​

Answer 1

Answer:

• For real and enlarged image, magnification be more than 1 and will be in negative.

* Dear user I don't know what is option (c) is given but option (a), (b) and (d) are not correct options for this question. But for real and enlarged image, magnification be more than 1 and will be in negative.

Knowledge required:

• If the magnification produced by a spherical mirror is in negative then the mirror is always “Concave Mirror.”

• If the magnification produced by a spherical mirror is in positive then the mirror is always “Convex Mirror.”

• If magnification is negative in a concave mirror then it's nature is “Real and Inverted” always.

• If magnification is positive in a concave mirror then it's nature is “Virtual and Erect” always.

• If in the ± magnification, magnitude > 1 then the image formed is “Enlarged”.

• If in the ± magnification, magnitude < 1 then the image formed is “Diminished”.

• If in the ± magnification, magnitude = 1 then the image formed is “Same sized”.

Additional information:

• If the focal length is positive then the mirror is “Convex Mirror.”

• If the focal length is negative then the mirror is “Concave Mirror.”

• The radius of curvature of concave mirror is always negative.

• The radius of curvature of convex mirror is always positive. $\:$
