From optics, when light passes from one medium to another, it
bends according to Snell’s law of refraction, until it reaches the
critical angle, as defined by the ratio of the incident index of
refraction to the outgoing index of refraction. Let light incident
along the normal to the refracting surface be defined as having an
angle of 0. Write a program that calculates the sine of the
outgoing angle and plot it versus the sine of the incident angle...
