In which of the following cases, a bright image is produced
In which of the following cases, a bright image is produced
The correct option is A the image formed by a concave mirror
Explanation for correct option
A: the image formed by a concave mirror
Since, the concave mirror has lesser absorption power than the convex lens , the image formed by it will be brighter than the image formed by the convex lens.
Explanation for wrong options
B: the image formed by the convex lens
The absorption power of convex lens and is more than that of the concave mirror. So, image formed by it will be dimmer than image formed by the concave mirror.
C: the image formed due to total internal reflection of light
Total internal reflection works on the condition that angle of incidence should be either greater than or equal to the critical angle, which here results in a dimmer image .
Hence, among the given options, option (A) is correct. A bright image is produced when the image is formed by a concave mirror.
