Two mirrors are placed at a 90
Explanation / Answer
1 since the reflection takes place at two surfaces infinite times hence miltiple
Images will be formed
B image C will be displayed
2 real inverted and larger in size
3 erect virtual and diminished
4as we move away from the pole the virtual image size will get smaller
B image size will get larger and the image will remain inverted
5 d=1.1 metre
Angle of incidence for second mirror =53.5
