Vedclass · Answer

(C) The boy's height is $H = 1.5\,m$ and his eye level is $h_e = 1.4\,m$. The distance from his eyes to the top of his head is $1.5 - 1.4 = 0.1\,m$. The distance from his eyes to his feet is $1.4\,m$.For a person to see their full image,the mirror must cover the range from half the distance to the head to half the distance to the feet relative to the eye level.Required mirror height above eye level: $0.1 / 2 = 0.05\,m$.Required mirror height below eye level: $1.4 / 2 = 0.7\,m$.The mirror's lower edge is at $0.8\,m$ from the floor. Since the eye level is at $1.4\,m$,the lower edge of the mirror is $1.4 - 0.8 = 0.6\,m$ below the eye level.Since the required distance below the eye level is $0.7\,m$ and the mirror only extends $0.6\,m$ below the eye level,the boy cannot see his feet.

$A$ boy of height $1.5\,m$ with his eye level at $1.4\,m$ stands before a plane mirror of length $0.75\,m$ fixed on the wall. The height of the lower edge of the mirror above the floor is $0.8\,m$. Which of the following is true?
