Standing somewhere between two vertical mirrors, you hold a lantern and at $t=0$ emit a light pulse that travels in all directions. You observe the pulse reflected from the mirror on your right at $t=2.5 \mu \mathrm{s}$ and from the mirror on your left at $t=6.5 \mu \mathrm{s}$. What is the distance between the two mirrors in your reference frame?
