Question

how can you explain the nature of the image formed by a plane mirror using the mirror formula?​

Answer 1

An image formed by a plane mirror is always straight and light ray does not emerge from the image itself.  

Explanation:

• A plane mirror is a surface that is reflective and flat. The images this mirror makes appear to be exactly the same as the real object.

• There are many characteristics of these images. One of them is the image is formed by this mirror are far behind than the actual placement of the object.

• The formula used to describe the image of plane mirror is 1/u + 1/v = 1/f = 2/R . Here v is image distance, f is focal length and R represents the curvature of the radius.

• While the radius of curvature can be found out using the given formula 1/u + 1/v = 0 means u = -v .

• Since R of plane surfaces will be large as compared to u and v of curved surfaces. Hence 2/R becomes zero.

• From this we can deduce, the image of the object placed in front of the mirror will be formed behind it.
