Question

If the magnification produced by a lens is -0.5, the correct statement is :

(a) the lens is concave

(b) the image is virtual

(c) the image is magnified

(d) the image is real and diminshed formed by a convex lens

Answer 1

Magnification is -0.5. The negative sign of magnification indicates that the image is real while 0.5 indicates that the image is diminished. A convex lens only forms a real and diminished image of an object. Hence, the correct answer is option (d).
