Question

A concave mirror produces three times magnified real image of an object placed at 10 cm in front of it.where is the image located?

Answer 1

use the reflection of concave mirror ray diagram to find it and also use the mirror formula

Answer 2

$\huge\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\pink{R}}}}$

magnification(m) = -3 (as image is real)

object distance(u)  = -10cm

image distance (v)=?

we know that   m= -v/u

-3 =  -v /-10

-3 = v/10

 

v =-3 * 10

v = - 30 cm

thus the image is 30 cm away from the concave mirror.
