Bright fringes are observed in reflected light

Reference no: EM13671839

Two flat pieces of glass that each has a length L = 20.0 cm are arranged by a fiber between them. The setup is illuminated by a yellow sodium light (590 nm), and 19 bright fringes are observed in reflected light.

What is the diameter of the fiber?
