Using the given apparatus, find the numerical aperture and acceptance angle of a glass-glass fiber.

A detector is placed at a distance 2 mm from a laser source emitting red light. Find the numerical aperture of the plastic-glass fiber used.

For different laser source, find the variation in numerical aperture and acceptance angle of a glasss-glass fiber with detector distance when the distance between the source and detector is 3 mm.

A plastic- glass fiber is used to transmitt blue light. Obtain the angle of incidence at which the light can be propagated through the fiber without any loss.

Compare the acceptance angle for a glass-glass fiber and a plastic-glass fiber for propagating green light without loss.
