Vedclass · Answer

(C) For a person of height $H$ to see their complete image in a plane mirror,the minimum length of the mirror required is $L = H/2$.Given $H = 170 \, cm$,the minimum length of the mirror is $L = 170/2 = 85 \, cm$. Thus,statement $(b)$ is correct.The bottom edge of the mirror should be placed at a height equal to half the distance from the ground to the eyes. Let $h$ be the height of the eyes from the ground.Given $h = 160 \, cm$,the height of the bottom of the mirror from the ground is $h/2 = 160/2 = 80 \, cm$. Thus,statement $(c)$ is correct.Therefore,the correct statements are $(b)$ and $(c)$.
