The equation i gave has nothing to do with total internal reflection though. None of what you just said has any relationship to the equation you were asked to try to work on.

The light is not bouncing off a hard boundry , where it would create a reflection. IT is passing through a **gradient** where the refractive index is changing continuously, not abruptly.

This means it never gets reflected but rather just bends continuously.

I hope that clear it up. Are you now able to understand the equation and how to calculate it.

Can you do the math or do you need help now that I've explained?

Keep in mind for me to approve of the idea of cops not being allowed guns no only would that have to be at a constitutional level but it would have to apply to **all** government and cvivilian agents within the borders of the country (with the exception of an invading force).

Which means I would not approve of something like the UK has where every day cops dont have guns but other types of cops do have guns and can be called in when needed.

It would have to be a complete ban on all guns within the borders of the nation. Not even the people protecting the president would be allowed guns in that case within their own borders unless an invasion is underway.

@namark

If we could ban such guns and ensure the government honors such a ban, then yes. But it would have to be encoded in the constitution of a country and very hard to change for it to work.

What part didnt you understand, I will step you through it. Remember we are trying to teach you here, so its important you attempt to work through the math yourself and we can correct it as you make mistakes. If you dont know how to do the math just ask and let me know what parts you dont understand and we can cover that.

No that is not what I said.

The path of the green beam you are seeing is **not** the path of light. The freen color your seeing is light.

If i light a lighter the flame glows. I presume you are educated enough to know the lighter isnt just spewing light out of the top, flames arent **made** of light, they simply **emit** light. That is what you are seeing there, light is being emited but the beam that creates it (And thus being bent) is an electron beam, not a light beam.

Just think about it, when you turn on a flashlight in a clear house with no fog, you dont see the light beam itself, but you do see the spotlight on the wall. Moreover if you put a magnet near a flaashlight the light spot it makes on the wall wont move or bed from the magnet.

It should be immediately obvious why, now, what you are seeing in that picture is not a magnet bending light.

This is also why i say you have to learn the basic math before you try to say things. Did you solve that equation i gave you earlier and a few minutes ago?

@adidasJack

If you need an example of what it looks like just go outside and look, thats a perfect example.

If you want to do the math itself, here is the post where I told you the math and how to calculate it when you posted your extremely **erroneous** math. I asked you to do the math again calculating in refractice index of the air.

Please do this and show your results so you can see why you were wrong. Here is the post where I include the equation for this:

@compass_straight_edge I also interact with all new users who post on our local time line. They do all appear to be real people. But yes it is partly related to the new indian users.

@adidasJack

Those arent pictures of the path light takes. Thus the bending your seeing is also not a bending of light. Those are cathode ray tubes. The paths you see is the path **electrons** take not light. They simply cause the gas to glow as they pass through it and then the gas emmits light (which is traveling in a straight line to your eyes).

@nonlinear @Froghat @the_daily_comfy @CCoinTradingIdeas

@nonlinear

Ahh yes, its very cool and a very common idea that physicists have shown. One of the fundamental properties of light is that it always travels in a straight path through space time.

@namark

Not so much that they wont shoot, only that they only will do so when they think the cause is worth risking their own lives.

Seems when talking about protesters history is against your assertion. Most cases in america I can think of where people were slaughtered en masse, especially protestors it was when the police knew for a fact no one could be armed (gun free zones).

As for armored bvehicals, thats why any reasonable law would state that any weapon or defense a police officer could buy is something a civial can also buy. So in such a case either armored vehicals are outlawed for both groups or they are availible to both groups.

@jump_spider

@adidasJack

Did you manage to do the math exercise I gave you yet where you calculate the distance to horizon from the refractional index of the air and curve of the earth?

@nonlinear @Froghat @the_daily_comfy @CCoinTradingIdeas

@namark

Presumably by the time you decide an uprising is needed you've already long since bought your guns or inherited them from your parents.

I dont think anyone wakes up one day and just decides to plan an uprising and goes out and buys their first gun.

@jump_spider

@nonlinear

Gravitational lensing doesnt bend light, it bends the space time itself. Light still travels in a straight line.

But even that aside for a second (As that is a bit of a linguistic double-speak I admit) we arent talking about mass. We are talking about how the velocity of a spaceship shooting out lasers doesnt effect the speed or the direction at which lasers come out. Which would be effected if space-time were made of a substance like an ether, which it doesnt.

I take it you just recently signed up.

Im the founder and admin of QOTO (A STEM based instance). Nice to meet you. Sounds like I'll be seeing you around in some STEM threads.

@adidasJack

We can continue later if you wish.

But you have to understand what we mean when we say it isnt a substance and why we pick a different word, it has to do with the fact that it behaves differently.

If it were a substance than the speed of a wave through it would be relative to the substance it moves through. A wave in the ocean has a speed that is relative to the water. No matter how fast I am moving relative to that wave wont change this fact.

With space-time fields this is different, they are relative to the observer and not some medium

Think of the experiment which we used to disprove the Ether. Its like this, lets say i shoot a bullet at a target and it hits the bullseye. If the next time i shoot there is a cross-wind then the bullet wont hit its target anymore. The reason is because the bullet moves through a medium (air) and so if the air moves the bullet is carried along with that air.

But EM doesnt behave that way. If i shoot an EM wave at some target it will always travel in a straight line. If i shoot EM based gun at a target it doesnt matter how fast me and the target (in this case earth) is moving through space it always travels in a straight line. If it were moving through a substance then the EM field would "bend" as that substance flows.

Again ether is the wrong term. You really mean "field" not "ether", it isnt made up of a substance thus ether is not appropeiate
