The diagram below shows a object O placed at the middle of two parallel mirrors. Which of the following is not a possible position of image of O?
Solutions: Option D
Based on the concept of characteristics of mirror image – Distance of object to mirror is equal to Distance of image to mirror.
Object O at the centre of two mirrors, based on the above characteristic, B and C are possible positions of image of O.
Consider A. Treating C as the object now and using the mirror on the left, distance of C to left mirror is equal to distance of A to left mirror.
Hence A is a possible position of image of O.
Consider D. Treating B as object and using the mirror on the right, distance of B to right mirror is not equal to distance of D to right mirror.
Hence D is not a possible position of image of O.
