NOTES – Refraction of Light - Helpline for ICSE Students (Class 10)
... Now that we are clear with What is Refraction, Let us concentrate on the Laws of Refraction. There are 2 laws of Refraction. First Law: The incident ray, the refracted ray and the normal all lies on the same plane. Second Law: Ratio of the sine of the angle of incidence to the sine of the angle of r ...

... The sign between kx and t determines the direction the wave travels along the x-axis. + wave travels to left (in the direction of decreasing x) - wave travels to right (in the direction of increasing x) The phase angle shifts the cosine or sine function left or right.

This is a characteristic of the medium in which light is propagated, and is determined by the Refractive index (n), or the relation between the velocity of propagation in a vacuum (c) and in the medium under consideration (v). n=c/v For this reason, the "n" of minerals is always greater than one (ra ...

7.1.3 Optimizing Light Confinement and Gain in Laser Diodes
... In order to have high efficiency and a single mode, we must maximize the density of photons, u(ν) and the gain g(ν) coefficient in the same active area of the device. This is not a condition automatically met, quite the opposite. The gain coefficient is mostly a function of the positions of the qua ...

Retroreflector
A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering. In a retroreflector an electromagnetic wavefront is reflected back along a vector that is parallel to but opposite in direction from the wave's source. The angle of incidence at which the device or surface reflects light in this way is greater than zero, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence.
