6(a) Critical angle is the angle of incidence in the optically denser medium for which the angleof refraction in the optically less dense medium is 90°(b)(i) In order for total internal reflection to occur, light ray must travel from an optically densermedium to an optically less dense ...
What is critical angle formula? The critical angle = the inverse function of the sine (refraction index / incident index). We have:θcrit= The critical angle. nr= refraction index. How do you calculate apparent depth? real depthapparentdepth=hh′=tanθ′tanθ=n. For water, n is about 4...

A light guide is a device used to direct light from a light source (commonly an LED) to a place where the light is needed. Light guides are also sometimes referred to as light pipes.

What is critical is the fact that the mass of the new atom is less than the sum of the lighter atoms' masses. As with fission, the "missing" mass is released in the form of heat - kinetic energy. One often-misinterpreted aspect of the energy-mass unification is that a system's mass...
