A person is in a room whose ceiling and two adjacent walls are mirrors. How many images are formed

Options

A. 5
B. 6
C. 7
D. 8

Answer

C

Explanation

Images form by adjacent wall `theta =90^(@)`
`n=(360)/(theta)=(360)/(90)=4`
number of image `=n-1=4-1=3`

`I_(1), I_(2), I_(3)` and O are object for ceiling then images form by ceiling = 4
Total number of images `= 3 + 4 = 7`
