No, the decrease in speed does not imply a decrease in the energy carried by the light wave. The energy of light depends on its frequency, which remains unchanged when transitioning between media. Only the wavelength and speed are affected, not the energy. For more visit here: https://www.tiwariacadRead more

The working of optical fibers is based on the principle of total internal reflection. When light travels through the core of the fiber, it is reflected entirely at the core-cladding interface, allowing efficient transmission over long distances.

Total internal reflection occurs when light travels from a denser medium to a rarer medium at an angle greater than the critical angle. The critical angle depends on the refractive indices of the two media. Additionally, the light must be incident on the boundary from the denser medium. For more visRead more
