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

Answer»

7 images will be formed by two adjacent WALLS and a ceiling all being plane mirrors.Explanation:The walls will act as two mirrors inclined to each others at 90° and so will form 360÷90(∅)=4.Since it is an even number HENCE TOTAL no. of images formed is 4-1 = 3 .Now these images with object(Person) will act as OBJECTS for the ceiling of the mirror and so ceiling will form 4 images as shown. Hence total no. of images formed is 3+4= 7.
