Answer:
1 .Rectilinear propagation describes the tendency of Electromagnetic waves (light) to travel in a straight line. Light only deviates from a straight line when the medium it is travelling through changes density. This is called refraction.
2. Refraction of Light and Laws of Refraction ... A ray of light striking normally on another optical medium does not suffer ... Conditions for a Light Ray to Pass Undeviated.
