Question

linear magnification of an image formed by a mirror is 3/2 the mirror is​

Answer 1

Answer:

ANSWER

Linear magnification produced by a spherical mirror is the ratio of the size of the image formed by the mirror so that of the size of the object.  

⇒ m=  

O

I

​  

 

where, I = Image size

And, O = Object size

Explanation:

Answer 2

Answer:

Concave Mirror

Explanation:

It has been given that the linear magnification of an image formed by a mirror is $\frac{3}{2}$.

We know that the linear magnification (m) of a concave mirror is simply the ratio of the size of the image, i.e., $h_{2}$ to the size of the object, i.e., $h_{1}$.

Therefore, $m = \frac{h_{2} }{h_{1} }$.

According to the given question,

$m = \frac{h_{2} }{h_{1} } = \frac{3}{2}$

Since the size of the image is greater than the size of the object and magnification comes out to be more than one, the mirror is concave.

Some characteristics of a concave mirror are as follows:

• The reflective surface of a concave mirror is curved inward and it is away from the source of light.
• The image formed by a concave mirror is enlarged, virtual and erect.
• Examples: It is extensively used as shaving mirrors, headlights, head mirrors, and so on.

Final Answer:

The linear magnification of an image formed by a mirror is $\frac{3}{2}$, the mirror is concave.
