/sci/ is there some sort of color equation I can use to assign colors to wavelengths?

I want 'true color' so black from 0 to 350nm, violet through to dark red (700nm) then black again. Fading in and out of black would be best.

I currently wondering if it is possible for an object which is smaller then a emission of electromagnetic light can emit that size of wave.
To give an example hydrogen and helium are the size of the ultraviolet and smaller spectrum would that mean it is impossible for them to emit inferred waves.

Alright, this is something I've been asking my professors lately, but they haven't exactly given a satisfactory answer.

We all know that electromagnetic waves have a frequency, radio at the low, gamma at the high. What I wonder though, is what occurs when the frequency is either extremely low, or extremely high, such that a graph would appear to be a single straight line rather than a sine wave.
Basically, have one wave with a frequency of infinity, and another with a period of infinity. Physics is not my major, but this is a question I think on often.

> inb4 trolling, I actually want to know this

Is the process of using a microwave to heat water an example of heat or work? Don't worry, this isn't homework. It was just a question that popped into my head in physics class. Since there is no "temperature" difference, there's not transfer of heat energy, but the microwaves aren't really doing work on the water molecules by forcing them to move, or are they?

I just had a radical idea guys. We all know the electromagnetic spectrum covers a wide range of frequencies right? And we all know that electromagnetic waves can propagate through empty space right? Well what if we used these waves to transmit INFORMATION?I know it's crazy but suppose we created a circuit that could somehow create these waves. We could then control the circuit and thereby control the frequency or amplitude of the wave produced. These differences in frequency and amplitude could then be used to represent different kinds of information.Think about how efficient it would be! What do you think about this guys? Should I build a prototype?

hey /sci/

I'm wondering if it is possible to get light to stop in midair in any sort of way. like if I was to use a projector, would there be a way to get it to seemingly stop in midair without the light having to come into contact with a solid object? Might using an electromagnetic field work?

Anyone know what studies are currently going on with gamma rays? I've been looking around but haven't found much.

Anything smaller than 10^-12 m is considered gamma. You'd need a fuckton of energy to get a photon with that small a wavelength though.

Chandra X-ray observatory doing that infrared oberservation.

ah, that makes sense.

i was thinking something along the lines of, perhaps the production of UV light is indeed some way inefficient and therefore produces radiation of a slightly lower frequency, ie. visible violet light?

What were some of the properties of the energy present during the big bang?

What wavelengths were present? At what amplitudes?
