Homework Statement
A young lady wants to see herself in a small mirror, the ear to ear width of her face is 6 in and eye to eye is 4 in. What should be the minimum width of a mirror so that she can see her face completely
Homework Equations
There a few equations which when directly applied give the required answer but i want this to be solved using pure ray optics...The Attempt at a Solution
I've applied simple ray optics such as angle of incidence being equal to angle of reflection,but what i don't understand is that don't we require the distance of face from the mirror ...please help
