Question

Explain how a hair dresser makes you see hair at the back of your head after the haircut is complete

Answer 1

Hi!

A hairdresser helps us look at the back of our hair by shining a mirror at the back of our hair. The reflection of our hair falls onto the mirror at the back which the hairdresser holds and that reflection gets reflected into the mirror infront of us which virtual image again gets reflected into our eyes and we can see the back of our hair.

Thank You
{Hope You Understand}

Answer 2

they use concave mirrors and make u sit in front of the mirror and put the concave mirror at your back as its focal length is more u can see ur hair in the mirror

hope it helps!!
