Light Refraction and Total Internal Reflection

Why did God create all this and leave us in this mystery?

This is how automatic windshield wipers work on your car. A water drop changes the path and changes the lasers path to the sensor, detecting the water on your windshield

This was better than I thought it was going to be

Ideas? Really?

According to Snell's law...😊

Then Lasers are a real thing.❤

that hurts my eyes

Dear Don't repeatedly expose your skin to Laser light! Plz it can cause DNA damage! Best wishes!

Is it bending, though? Isn't it more akin to the light slowing down and changing direction?

My enemies on war thunder:

I wonder if it's happening in this universe and what we see is not what is there.

These videos are fascinating! Kudos! 🔦

Do you sell these as a kit?

How come that to the camera the light is darker than the table?

What’s the difference between light bending and light curving

Wow what's more interesting is your pink glowing fingernails I'm sure that is unexplainable love your explaining light reflections

The light inside the medium of refractive index must be incident towards the interface at a critical angle for total internal reflection to occur.

Light when sin x > 1:

“something cool”

so scientists come up with these to keep themselves entertained at work

I caught my cat watching this

Laser Ray Box ... 🤣 Sounds like something out of an old Bugs Bunny, or Roadrunner cartoon. You should change the label to read "ACME LASER RAY BOX" ... 🧨💥

Is this the secret to time travel??

relevant for miltech, looking around corners

For a moment there it felt great understanding and nothing involving Jesus or any form of belief 😊

Man I wish science educators like this existed when I was a kid.

Show this to folks who are confused about how mirrors work.

Isaac Newton may be the most amazing person that ever existed.

I understand what, but for the life of me don't think I'll ever understand why.

Critical angle

Yeah and light can't hit that giant block subtitle

Any light lost?

Changes in vacuum but stacks in the air?

ooooh. ahhhhh

Can some one give me a solution catch loud music and throw back to those who play to lud music because I am frustrated to tolerate them and looking for solution

Wish this were in our school

I’m reminded of the Dark side of the moon cover.

Angle is called Critical Angle needed for TIR

Even Dslrs Use This

That "thumping", annoying background "music" ruined the video and earns this channel yet another thumbs down .

Think ligth is a wave

What i want to know is where can i buy that laser ray box

wifi does at least similar things. I'm not sure though whether it does the total internal reflection like that though. you know that?

When I did this in school, my partner didn’t have time to draw their diagram, so I gave them mine and I quickly traced my design in rough for me to use

Then, my teacher came up to me and starting berating me for how it looked and used my “partner’s” work as an example of good work



Both designs were mine.

Would a shape like a cylinder mostly trap the laser if hit at the right angle?

What about an Octagon? Would it continuously make a internal reflection?

i learned this from rpg puzzles

"When the world needed him most, he returned."

nice lesson
