Requirements
• Basic high school algebra. (Should be able to solve for x and y given x+y = 4 and 2x - 3y = 15)
• And little bit.. TInnie winnie about refraction and snells law ( I will include notes covering that part don't worry)
Description

This course will cover the basics of Wave optics. It will be revolving majorly around the concept of
Interference and Diffraction

You ll see what they are, and how amazing they are, and how they play a role in our everyday lives (yes literally LITERALLY EVERYDAY). You ll understand (and not just FYI, but full quantitative analysis) why
Soap bubbles are colored, why some insects give out very bright colors (also feathers of peacock), why when you look at far away things, they blur (or pixelation if you prefer digitial :P) and a lot more other stuff.

If you are a high school student taking up a physics course or going to take up, anything at AP level or below, this is recommended for you

The structure of the course is pretty standard, Everything is in videos. There are two modes.

The float head -> where you will see my head talking about concepts with animations

The hands --> where you will see.. well my beautiful hands with which I write stuff like equations

I look forward to seeing you. Cheers!

Who is the target audience?
• This course is not for anyone who is not at all interested in physics
• This Course is for anyone (above 15 years probably) and is going to take up or taking any physics course at AP level or below

Going Back to 17th Century
1 Lecture 04:23

In this introductory video I ll talk about two amazing theories by two well known (at least 1 well known, and the other will be well known to you after you finish this course :D) scientists to explain what light is.

Let the theories begin!

Newton Vs Huygen
6 Lectures 30:58

Reflection is easy peezy for Sir Issac Newton. The man who unified gravity can surely explain reflection of light!

Newton explains reflection
04:52

Refraction must also be easy for this guy right? I mean how hard is to explain why light bends. Check out Newton's simple idea that even derives Snell's law of refraction. What a victory for particle model! (Spoilers: Or is it?)

Newton tells why light bends
04:28

Ok now I know this guy isn't all that famous, but you have to hear him out. You have to understand his wave theory. Its a great idea. And he believed in it so much, he went against the Mastero of his time, Newton. So what is light according to Huygen?. Find out in this section!

Huygen's Wave principle
06:44

If Newton can do it, So can Huygen. Watch as he explains how wave theory can prove the laws of reflections!

Huygen's turn - Reflection
06:20

This is a true test of the wave theory. Refraction, bending, how does his theory tackle refraction? Newton derived Snell's law. Can Huygen do it too? Or will his theory perish? (Spoilers : This is Wave optics for crying it out loud )

Huygen - light why you bend?
06:21

If you have been following, then by the end of the previous video you must have had your jaw dropped. So pick it up. Yes they both derive Snell's law, and both come to quite dramatic and contrasting conclusions

They both agree, refraction is due to change of speed of light. But what do they disagree on? Lets compare the results shall we?

Contrasting results HOLY MOLY!?

Light is a Wave Or Particles? :O
2 Lectures 04:52

So the moment of truth? Who is right? who is wrong?? particle or wave?
(Spoilers : really?! I don't think you need any more spoilers)
