Question

a man sits in an Opticians chair looking into a plane mirror which is 2 metre away from him and views the image of a chart which face is the mirror and is 50 cm behind his head how far away from his eyes does the chart appear to be ​

Answer 1

Answer:

Distance between the man and the mirror = 2 cm

Distance between man and chart = 50 cm = 0.5 m

Distance between chart and mirror = 0.5 m + 2 m = 2.5 m

Distance between mirror and the image of the chart = 2.5 m

Distance between man and the image of chart = Distance between man and the mirror + Distance between mirror and the image of the chart

= 2 m + 2.5 m = 4.5 m

hope it's help u.....

Answer 2

Answer:

4.5 m

Explanation:

distance between mirror and man = 2m

distance between man and chart =50cm

1cm=1/100 m

50= 0.5m

distance between mirror and chart = 0.5+ 2= 2.5

distance between image of chart and man = 2+ 2.5= 4.5 ANS
