Introduction to Photonics | Session 3 | Problem Solving | NPTEL

Good afternoon, everyone. Uh this is a live session for the uh course which is entitled as introduction to photonics. And this is the live session third. So, we are going to discuss about the uh this week which is uh week three of the course content. And after that, followed by that, we will go for the uh

few question answer sessions. Uh and doubt sessions also. I hope that uh my voice is clear to you. Can you please uh confirm am I audible or not?

Okay, so let's move towards the Okay, so let's move towards the first uh brief description about the this week's lecture. So, I will go step by step with the previous classes. Start from the week one day one class. So, the professor has already discussed all the informations, all the studies about the electromagnetic waves.

Electromagnetic wave nature of light in detail, in depth. Also, he has given so many examples of the phenomena using the application also. And has been demonstrated multiple applications using this concept. So, here we are going to discuss a little brief intro about the electromagnetic wave to quantum particles. So, basically we have already learned

about the ray nature of light in the way week one, and there we discuss about the refraction, reflection, all the phenomena, even the applications. After that, we have gone to the wave nature of light after ray nature followed by wave nature in the week two. And we have discussed in depth and discussion about the

diffraction, interference, and so many concepts including the applications of each phenomena. Now, we are going to discuss about the electromagnetic wave nature of the light. And for that, we have to go for the fundamental rules of the propagation. As we know that the light electromagnetic radiations were established by the Maxwell's equation where the there are four equations he
