If you measure a ‘white’ LED with a spectrometer, you’ll see it’s made up from primarily yellow and a bit of blue, as verified by the data sheets. There no such thing as a full spectrum LED at least yet. This may be a confusing point to those new to the world of photonics. I used to build Quantum Efficiency devices to measure the efficiency of solar cells of all sorts, and can arrest to the value of LEDs in this undertaking.

GreenAppelPie, check out yuji LEDs. Their spectrography show a pretty solid spread for both 6500k and 3200k at 98 cri a and equally hich TCLI. Of course, that is the phosphor impregnated silicone and not the actual emmiter which is UV (as opposed to typical 450nm).

Hey Keystone, I have something u may be interested on. Over 0.016A Flowing through your body is where we can no longer let go. 0.05A is lethal and 0.1A can stop your heart. But resistance in our body blocks the current flowing in us, here's how: Voltage÷YourResistance×Current or (V÷BR×A) For Ex: My body Resistance is 180KOhms, and I touch an AC outlet of 120V and 10A. How am I not dead? It's because there's 6mA out of 16mA flowing, which is not lethal enough.

I have a question: If everything is made up of particles, or quanta, then what is a magnetic field? I’m not asking for a description of what that field does but rather what physical quantum particles actually make up the field.
@KeystoneScience 6 жыл бұрын
Honestly, I, nor really any one knows, some people theorize that it is a product of particles, like the theorized graviton, however this should mean that magnetic fields are bent by gravity, which I doubt they are... or at least much... others consider it to be a layer of the universe, kind of like another dimensional layer where we see a projection in 3 space of the effects of the bending of that layer by means of charge. Another question is how does the electron know to be attracted to the proton, if we imagine particles going out, we would expect everything to be repulsive to one another, so, this is another thing that is just referred to as a Feild. In short, no one really knows, or at least no one has proven a theory (as far as I know ) on what these effects actually are, so stay thinking on it!!!

@Ploinkish 6 жыл бұрын
The magnetic field is actually the same as the electric field, is just boosted into another reverence frame (Veritasium has a very nice video on that). But both are compounds of the electromagnetic force, which is based on the exchange of photons. So the particles of the magnetic field are photons.

I’m not quite certain what you mean, although E=γmc^2 + pc, since a photon is treated as massless, the mc^2 part is 0, however, it does still have a momentum component due to symmetry, so we have E=pc, and p=h*f/c , so E= h*f/c *c = hf = hc/λ . And that is what we used. Although perhaps I am misunderstanding your comment, did this help in any way?
