Question

Write the characteristics of image if m=0.2

Answer 1

magnification (m)= Height of image / Height of object

or –(image distance)/object distance

→if m=-2

real , inverted and enlarged image if formed.(2 times of object)

→if m=2

real, erect, enlarged image is formed.

→if m=-0.2

=-2/10=-1/5

virtual, inverted and diminished image is formed.

→if m=0.2=1/5

virtual, erect, diminished image is formed

→if m=-1

real, inverted and same size image is formed

→if m=1

real, erect and same size image is formed.

according to sign convention,

minus symbol in numerator indicates inverted image
