Homework Statement
Consider a bathroom mirror with a glass sheet of thickness d and an index of refraction n. Your face is located at a distance h from the front surface of the galss sheet. a
a. find the position of the image of your face that you see due to the reflection from the front surface of the glass
b. find the position of the image of your face that you see due to the reflection from the mirror surface behind the glass. Take into accound the effects of refraction at the glass-air interface.
Homework Equations
na/s + nb/s' = (nb - na)/R
1/s + 1/s' = 1/f
The Attempt at a Solution
for part a, we know that the image is a distance of h behind the glass, thus s' = -h. However, I'm not sure what to do for the second part.
the answer to part b is h+2d/n, but I'm not sure how to get there. If someone could help me that would be much appreciated. Thank you
