Light Clocks!

Just a small detour here. To understand what I said in the previous post, better lets look at a light clock. Well, what is a light clock? A light clock looks like this one below:

It is a little square carriage made of glass on wheels. At least this one is. Inside there are 2 mirror exactly opposite. One on the floor and the other on the roof. At the bottom mirror there is a light source. If you looked at the diagram it would make it clear in your mind. Yes, we have wheels on it. This is to conduct an experiement that will make it really fun!

We all know that Time= Distance/speed. That means if I was to go 100 miles at 50MPH. The time taken will be 2 Hours to complete that 100 miles. Simple.

In the light clock the distance light travels, is twice the length of the clock. That is light starts at the bottom, goes to the roof and then comes back to the ground. We also know that it will travel at 186,000 miles/second.

With a light clock,

Time= 2L/C. Where L is the hight of the clock and C is the speed of light. Which is 186,000 Miles/Second or 300,000 Kilometres/Second depending on which system of measure you want to use.The above sounds simple, and it is simple. The fun begins when the light clock it self moves. That is where Mr.Lorentz comes in. Again, read the post I had explained that in.
