Question 1 A light propagates inside a single step index fiber with a speed of 2.0013 × 108?/? and has a total internal reflection. Note that, the light emitted from a laser source and with an acceptance angle of 5.4370 , the ray strikes the interface between the air and the core of the optical fiber, thus a refraction and reflection occurred. i. Determine the core diameter for the fiber to permit its operation over the wavelength range 1.48m to 1.60m. [] ii. Calculate the new fiber core diameter to enable single mode transmission at a wavelength of 1.30m.

Radiation

Radiation can be described as the energy in the form of a particular matter or electromagnetic waves traveling in the air and can be in the form of light, sound, and heat. Radiation can be detected through special instruments like X-rays. The radiation from a cooler object is less intense as compared to the radiation from hot objects.
