Question

The place you get your hair cut has two nearly parallel mirrors 7.50 m apart. As you sit in the chair, your head is 1.00 m from the nearer mirror. Looking toward this mirror, you first see your face and then, farther away, the back of your head. (The mirrors need to be slightly nonparallel for you to be able to see the back of your head, but you can treat them as parallel in this problem.) How far away does the back of your head appear to be

Answer 1

the far distance is 15 meters

Step-by-step explanation:

The computation is shown below

The Light from the back of your head must be

= 7.50m - 1.00m

= 6.50m

It should be the back mirror.

Now 7 m to front mirror and 1.00 m from the front mirror to

Therefore you see the back of your head is

= 7.50m + 1.00m + 6.50m

= 15 meters away

Hence, the far distance is 15 meters
