Question

A candle is placed 14 cm in front of a concave mirror. The image of the candle is focused on a sheet of paper that is exactly 21 cm in front of the mirror. what is the magnification of the image

Answer 1

The magnification of the image is
`M = -1.5`

Step-by-step explanation:

From the question we are told that

The object distance is
`u = 14 cm`

The image distance is
`v = 21 \ cm`

The magnification of the image is mathematically represented as

`M = - (v)/(u)`

substituting values

`M = - (21)/(14)`

`M = -1.5`

The negative value means that the image is real , inverted and enlarged
