draw a triagle ... with the eye in the center of the mirror
ok so the equation should be for the width an comarison relating the distances... 1.5/1.3=.5/x
which is half of the mirror.... which is .433333.... so the width should be .86666m
same with the height....
1.5/.3=.5/x
=.1m that is the height of half of it.... which is .2 meters for the entirety
that seems excesive for the lengths of a rear view mirror.... maybe the factor of 2 is wrong...
it is either .4333 or .8666
but whatever the case.... the angle of refraction is the same as the angle of reflection... meaning whatever angle you look at a mirror... the light you see will be coming 2 times that angle..... like an isoceleleleles triangle .... so if you were looking at the mirror from the bottom left corner... then you would not multiply the numbers by two... but if you were looking from the center of the mirror you would
