light isn't a "transverse wave in the Aether," instead light is a wave in magnetic and electric fields where the field vectors point sideways. But the flux lines themselves don't wiggle sideways, and the flux doesn't contain any sine-wave shapes. Take a look at the video below left. ...
Heat is the most common way we see light being generated -- a normal 75-watt incandescent bulb is generating light by using electricity to create heat. Electricity runs through a tungsten filament housed inside a glass sphere. Because the filament is so thin, it offers a good bit of resista...

Watt hours (Wh), sometimes written W.h, can measure either electrical energyproduced, say by a power station, or Watts can measure the amount of electrical energyconsumed(say at a light bulb or an air conditioner in our home). For air conditioners, the A/C units' total Wh is the energ...
into shape. After the glass cooled, they attached electrodes to each end and removed the air with a vacuum pump. Then, they passed a high voltage current through the tube to remove any impurities on the inside of the glass. Finally, they p...
