Question

define magnification of lens and mirror what does it signify​

Answer 1

Answer:

Magnification = height of the image/height of the object = distance of the image/distance of the object. The magnification produced by a plane mirror is +1 means then the size of the image is equal to the size of the object.

Answer 2

$\huge\boxed{\underline{\mathbb{\red{A}\green{n}\pink{S}\orange{w}\blue{E}\pink{r:-}}}}$

☞ Magnification :

/→ It is the ratio of size of image to that size of object .

m = h'/h.

/→ It gives us the idea by what factor the image is smaller or larger than the object.

/→ eg: if m = 2 , then it means that the image is 2× in size as the object.
