Question

The ratio of the height of the image to the height of the object is called:

पर्याय

• Magnification

• Power

• Refractive index

• Focal length

Answer 1

Magnification is defined as the ratio of the height of the image to the height of the object. Mathematically, it is expressed as \[m=\frac{h_i}{h_o}\], and for a thin lens it also equals \[\frac{v}{u}\].
