9. For a multimode step index fiber, the refractive indices of core and cladding are 1.53 and 1.50 respectively. If the radius of core is 50 pm, calculate the Numerical Aperture, Acceptance angle, normalized frequency of the fiber (i.e, V number) and number of guided modes. The wavelength of light propagated is 1 pm. What should be the largest radius of this fiber so that it is a single mode step index fiber.

9. For a multimode step index fiber, the refractive indices of core and cladding are 1.53
and 1.50 respectively. If the radius of core is 50 um, calculate the Numerical Aperture,
Acceptance angle, normalized frequency of the fiber (i.e, V number) and number of
guided modes. The wavelength of light propagated is 1 pm. What should be the largest
radius of this fiber so that it is a single mode step index fiber.
