Module1-Class1: Postulates and Rules

The learning objectives of this video are:
Understand that light travels in the form of rays in Geometrical/Ray Optics
Understand the physical meaning of the refractive index
Understand that light travels in the form of straight rays if the medium is homogeneous (i.e., refractive index = constant).
Estimate the reflected and refracted angles in a planar interface
Apply Snell’s law in one and two planar interfaces
