The reason we dont use wireless electricity was given by Tesla's investors when they withdrew the money: "where are we going to put the meter if electricity comes by the air?" that's the reason, the same reason wars are organized everywhere" greed.
Blue Twin Laser Cannon activate!!! Ever since I was a child I've wondered why does the blue twin laser cannon destroy more baddies in Raptor game on DOS than any other weapon, but in those days I only enjoyed the destructive force on display on my screen. Now I know, it's because blue is more intense laser light.
I came here from Netflix watching the movie 'Plane' where the main actor Gerard Butler commands his co-pilot to keep eyes on the 'GYRO'. I wasn't convinced with Siri's answer (Gyro is a food item😂), found that gyro was short for gyroscope, and being a visual person wanted to see a gyroscope to understand it! Halfof the video went above my head as you're WAY more intelligent than me but I subscribed anyway :)
What about if you do a disk on what scale you need it (usually in the microns/nano size) and add bumps around the edges. So then you will have a bumpy circle. Then you shine light horizontal to it and have the sensor looking at it from above. So as you rotate the disk, it shows different wavelengths as the disk rotates. You would have to also figure out how to cancel the rest of the scattering light so it can be accurate but I’m sure there can be a more better idea than what I just proposed. I’m not a know it all, I just like being creative and thing of the “what if’s”.
A Light Emitting Diode (LED) is a remarkable electronic device that converts electrical energy into light using semiconductor materials. At its core, a LED has two slightly different semiconductor layers. When an electron moves between these layers, it loses energy in the form of a photon, and this process generates light. The specific energy lost determines the color, giving us a wide range of colors from red to violet. For white LEDs, the process involves a blue LED coated with a phosphor. The phosphor absorbs some of the blue light and re-emits it as a lower-energy yellow light. The combination of remaining blue and emitted yellow light creates the white light we see. This simple yet elegant mechanism has revolutionized lighting technology, making LEDs efficient, durable, and versatile.
Why is it that our local transformer does not obey back emf because if it obey it then I high tension suppose not to power more than 1 transformer but an high can power a town why
The current in the secondary coil is very small, almost zero. So how can there be a toroidal magnetic field? Since the current is almost zero, but is calculated as non-zero, there is still a magnetic field in the secondary coil. But that magnetic field is not the factor that makes the LED light up when approaching. Actually, the light bulb is due to another type of electricity, which is electromagnetic radiation.
