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

The image is located 30 cm on the same side of mirror

Answer 2

Answer:

Real Image is inverted,So magnification is negative.

Thus,

$m = - 3 = \frac{image \: size}{object \: size}$

$\frac{hi}{ho} = \frac{ - v}{u}$

[Where v = image distance and u = object distance]

$\: - 3 = \frac{ - v}{ - 10} </p><p>$

$- 3 = \frac{v}{10}$

Image Distance(v) = -30cm
