  Is the light that comes out of fire an electromagnetic wave?

Mr. Faraday LIGHT was said to be an electromagnetic wave, He explained it as " Electricity creates MAGNETISM and if we move this magnetic energy it again produces electricity, and so on it a forward pulsing process which happens at the only speed of 670 million miles/ hour which is nothing but speed of light. So they both proposed the fact that light is an electromagnetic wave." Now question is that we also see light when we create fire, so the 1. Light which we see is the same electromagnetic wave that is explained by Mr. Faraday? 2. If it so how could a element (fire) that is created out of friction can produce the so called electromagnetic wave? 3. If it is not that electromagnetic wave, then what form of light is that we are looking at from a fire and how light takes that form?

    Just a minor historical point: it was James Clerk Maxwell who proposed that light is an electromagnetical wave, not Faraday.

But automobiles and etc there are pre-fixed standards like boiling point, flash point, volatility etc, we can check all these things but dedicated hard work required to test different oils and at different compositions. i wish we will see these biodegradable natural lubricating oils.

  Is there a way of customising LED's to a different size and shape?

I have experimented with putting LED's into 3D printed cubes, but there is a big fall off at the corners and edges. So I wondered if LEDs were customizable so that they actually were light source and cube?

However, the mechanism by which light isAn LED is a good example of a potted circuit. In essence the transparent portion of the device, is just a clear epoxy resin and can be shaped in any shape. However, the mechanism by which light is reflected from the bottom of the diode, is usually a cup shaped reflector that sits right under the actual diode and projects the light towards the lens at the tip. The lens which is often a drop of slightly different resin, determines the spread of the light from it's focus. You can make your own LED's using Quantum Dot technology and a UV frequency diode, where you put the QD device into the focus of the UV diode, and it flouresces at it's native frequency. Because it flouresces at 360 degrees, it will only loose light where it is shadowed by the electronic components. The next trick is to use a milky or translucent epoxy instead of clear, this causes the whole LED to light up instead of just the area around the QD device. If you burry it in a custom shaped pot based on the translucent material, you should be able to get a better lit cube.

    Wave is not a physical body, it is a phenomenon. It is a perturbation which propagates in physical field or a physical field is propagating in empty space.

  I can't find anything that will work efficiently. It has to be something that is commercially available not something that I have to synthesize in a beaker.

That wheel and reversion is very critical since the counter pressure is a thing to win and 'transferred'. The idea is to allow the minimum of losses, that by the way, are not directly LINEAR to the main potential. There are hooks with kind of spring and not so hard to be done by skilled people. In a simulation those hooks are going to follow 'instructions... 8) The sketch you sent will for sure cause big friction and force the elements to counter turn, due to mechanical touch. Thanks a lot!

The application ofWe have got an equipment and technology for determination of residual stresses. They are based on the hole-drilling method and electron speckle interferometry (ESPI-HD method). The application of electron speckle-interferometry unlike strain measurements with gages allows receiving bigger amount of displacement data around drilled holes without averaging. The method has all advantages of conventional hole drilling method (standard ASTM E837 ) but gives additional possibility to get an extra information about distribution of RS. For example, it is possible to make measurements on a weld reinforcement and we don't need to remove it (removing can cause redistribution of stresses) or it is possible to use experimental data only from one side of the area around a drilled hole (it is convenient for measurements near edges, stiffeners) and so on. We've extended application of the ESPI-HD method for determination of RS in a specific conditions such as presence of surface curvature (tubes of a small diameter), small object thickness (from 2 mm) and others. At the moment I am interested in the development of our method for the determination of residual stresses in orthotropic materials (composite materials,etc.). If you are interested in the determination of residual stresses in your samples, we could collaborate and conduct a joint scientific research.
