Ray Optics : Rectilinear Propogation of Light and Laws of Reflection

There is one thing not many people know about Science: It’s very simple!! Yes, you heard it right. Behind numerous formulae, derivations and problems, are fewer and simpler laws that, if mastered, can condense the bulk of syllabus into a handful of concepts.

At BYJU’S classes, we are trying to introduce people to the simplicity and beauty of science with our innovative learning techniques. Keeping in line with this motto of ours, we have come up with this article series titled ‘A single concept to explain everything in Ray Optics’ where we will explain the entire theory of Ray optics using a single idea.

In the first article of the series, we will learn about the rectilinear Propagation Of Light and Laws of Reflection. Excited? Let’s get started.

Important Ray Optic Laws

We are all aware of the fundamental laws concerning ray optics which in the simplest terms can be stated as:

  1. Rectilinear propagation of light: Light travels in a straight line.
  2. Law of reflection: Angle of incidence equals the angle of reflection.

Now we are going to be a little more courageous and ask why? Why does light behave the way it does? So are you excited? Please let us know how we may help you further with your JEE preparations in the comments section.
