Question

Define linear magnification.Does it have any unit ?Why or why not?

Answer 1

Hey Dear ... ✌️

=) Linear magnification is the ratio of the distance between the image and the pole(v) and the object and the pole (u). OR Its the ratio of the height of the image(I) to the height of the object (O).

It is unitless .

Hope , It Helps ... ❤️

Answer 2

Answer:

linear magnification: if an object lies perpendicular to the principal axis then the ratio of the height of its image to its own height is called linear magnification of the image

• it does not have any unit
• since it is the ratio of size of its image to its own size therefore it is dimensionally constant
