PPSC Physics Topic 4 MCQ Test With Answer

An important topic in the PPSC Physics Test is Geometrical Optics. In the field of Geometrical Optics, physicists study the propagation and behavior of light with the help of abstract mathematical rays. The process of abstraction of the concept of light makes it easier for the physicists to study the light when it goes from one place to the other or strikes with some material. Our understanding of the universe is nothing without the visible light that allows us to see things with our naked eyes. The importance of Geometrical Optics is therefore fundamental in the study of Physics as it enables us to understand how we see and what improvements we can make to see things better.
