Question

What is the magnification of v=0.6 and u = -1​

Answer 1

Answer:

Magnification of lens M=uv. (a) Magnification is −0.6, it will be Convex lens (since image is real , inverted and diminished)

Answer 2

Answer:

Magnification of lens M=uv

(a) Magnification is −0.6, it will be Convex lens (since image is real , inverted and diminished).

(b) Magnification is 0.6, it will be Concave lens (since image is virtual , erect and diminished). 

Explanation:

Magnification of lens M=uv

(a) Magnification is −0.6, it will be Convex lens (since image is real , inverted and diminished).

(b) Magnification is 0.6, it will be Concave lens (since image is virtual , erect and diminished).
