Question
A man of height 170 cm wants to see his complete image in a plane mirror (while standing ). His eyes are at a height of 160 cm from the ground.
Options
A.Minimum length of the mirror = 80 cm
B.Minimum length of the mirror = 85 cm
C.Bottom of the mirror should at a height 80 cm
D.
Required length of mirror = M1M2 So the mirror should be the length of half of thew size of man =
= 85 cm & it is placed such that its lower edge at a half the height of eye level height.
Required length of mirror = M1M2 So the mirror should be the length of half of thew size of man =
= 85 cm & it is placed such that its lower edge at a half the height of eye level height.Solution
