Detailed Solution
Download Solution PDFGiven:
- An object is placed in front of a concave mirror
- Focal length, f = -12 cm(since it is a concave mirror so f is negative)
- Object distance, u = -8 cm.
Formula Used:
Mirror Formula, \({1 \over f} = {1 \over v}+ {1 \over u}\)
Calculations:
Using the mirror formula, we get
\({1 \over f} = {1 \over v}+ {1 \over u}\\ \implies {-1 \over 12} = {1 \over v}+ {-1 \over 8}\\ \implies {1 \over v} = {-1 \over 12} +{1 \over 8}\\ \implies {1 \over v} ={1 \over24} \\ \implies v = 24 cm\)
Therefore, the image of the concave mirror is formed at a distance (v) of 24 cm.
