Question

An object is placed at a distance of 24 cm in front of a spherical mirror of magnification +1/3.
What is the distance of the image from the mirror. Also find the nature of the mirror.​

Answer 1

Answer:

Given that; Object distance (u) = -24cm; Image distance (v) = -12cm (image is in front of mirror hence v is negative). Now; Magnification = - vuvu ⇒ Magnification = - −12−24−12−24 = - 1212 ∴ Magnification is -0.5. Which tells that image is real and inverted and half of the size of the object.

Answer 2

Explanation:

m = -v/u

m= 1/3, u= 24 ,v=?

1/3 = -v/24

-v = 8

v = -8

the image distance is negative, hence the image is real, inverted.

the mirror is a concave mirror.
