- Homework Statement
- Derive the optical law of reflection. Hint: Let light go from the point A (x1, y1) to B (x2, y,2) via an arbitrary point P = (x, 0) on a mirror along the x axis. Set dt/dx = (n/c) dD/dx = 0, where D = distance APB, and show that then theta = phi.
- Relevant Equations
- t = nD/c

Relevant Equations: t = nD/c
I already derived the optical law of refraction with the information given. However, I want to know why dt/dx = 0. How do I know it?
