What is the law of reflection to the object, when it's perpendicular to the reflective surface. For example, if you face a mirror and stare eye to eye with the reflection- what is the angle?If I have understood correctly, the angle of incidence/reflection is equal, so if for the mirror is reflecting straight back, does this make the angle zero?I am confused because in the school book they gave us the angle is always slanted (example 45 degrees/90 http://farside.ph.utexas.edu/teaching/316/lectures/img1298.png ) but this question relates to your own reflection directly facing a plain mirror.
thank you very much
