A light ray in the core (n=1.40) of a cylindrical optical fiber is incident on the cladding. A ray is transmitted through the cladding (n= 1.20) and into the air. The emerging ray makes an angle 02 = 6.10° with the outside surface of the cladding. What angle 01 did the ray in the core make with the axis? Air

Components of some computers communicate with each other through optical fibers having an index of refraction n = 1.65. What time in nanoseconds is required for a signal to travel 0.17 m through such a fiber?  ns

A laser beam shines along the surface of a block of transparent material. (See the figure .) Half of the beam goes straight to a detector, while the other half travels through the block and then hits the detector. The time delay between the arrival of the two light beams at the detector is 6.10 ns.
