Question

An object is located 25.0 cm from a convex mirror. The image distance is -50.0 cm. What is the magnification?

Answer 1

+2

Step-by-step explanation:

m = -di/do

m = -(-50)/25 = 2

Answer 2

`\boxed{\sf Magnification \ (m) = 2}`

Given:

Object distance (u) = 25.0 cm

Image distance (v) = -50.0 cm

To Find:

Magnification (m)

Step-by-step explanation:

`\boxed{\bold{\sf Magnification \: (m) = - (Image \: distance \: (v))/(Object \: distance \: (u))}}`

Substituting values of Image distance(v) & Object distance (u) in the equation:

`\sf \implies m = - (( - 50))/(25)`

-(-50) = 50:

`\sf \implies m = (50)/(25)`

`\sf \implies m = \frac{2 * \cancel{25}}{ \cancel{25}}`

`\sf \implies m = 2`
