Question

the magnification produced by a spherical lens and a spherical mirror is + 0.8 what is the nature and lens and mirror​

Answer 1

Hey buddy

➡since , magnification produced by both spherical lens and mirror is positive .

➡therefore ,

1. Spherical lens = convex lens

2. Spherical mirror = convex mirror

Answer 2

Answer:

Explanation:

u = Object distance

v = Image distance

$h_u$= Object height

$h_v$= Image height

Magnification

$m=-\frac{v}{u}$

Consider object distance as positive. In order for the magnification to be positive the image distance has to be negative.

$m=\frac{h_v}{h_u}$

For magnification to be positive both the image and object have to be in the same orientation.

So, the image produced will be virtual and erect.

The same applies for the mirror also.

The image will be produced in the same side as the object for the lens. The image will be formed behind the mirror.
