The two plane faces are called are the refracting faces and the angle included between these two faces is called the angle of prism or the refracting angle . In the below figure (1), ABC represents the principal section of a glass-prism having ∠A as its refracting angle. A ray KL is incident on the face AB at the point F where N 1 LO is the normal and ∠i 1 is the angle of incidence. Since the refraction takes place from air to glass, therefore, the refracted ray LM bends toward the normal such that ∠r 1 is the angle of refraction. If µ be the refrac...

The four laws of thermodynamics govern the behaviour of these quantities and provide a quantitative description. William Thomson, in 1749, coined the term thermodynamics. The word “Thermodynamics” is derived from two Greek words “thermes” and “dynamikos” which means heat and powerful respectively.
