Question

a candle is held 3 cm away from the concave mirror of radius of curvature 24 cm .what will be the distance of image from the mirror

Answer 1

Hello Dear.

Here is the answer---

→→→→→→→→→

Object Distance(u)  = 3 cm (Negative)
Radius of the Curvature = 24 cm.

∴ Focal Length = R/2
        = 24/2
        = 12 cm (negative)

Using the Mirror's Formula,

    $\frac{1}{f} = \frac{1}{v} + \frac{1}{u}$
   $\frac{1}{-12} = \frac{1}{v} + \frac{1}{-3}$
   ⇒ v = 4 cm

∴ Distance of the Image from the Mirror is 4 cm (Positive).

Since, The Image Distance is positive, thus the Image is Real.
