LightBulb Incandescence BlackBody Simulation:
Used to measure the value of the fundamental Planck Constant (h) of Quantum Mechanics


White light, as from a candle, a fire, or the sun, has been known for several centuries to be composed of many different colors.
This property can be examined by shining such light through a prism, which then splits the light into its component parts.
A rainbow of colors is created, and in fact, the sky rainbow itself is a natural phenomenon which produces this color splitting.
Each color takes a slightly different path through the prism, or a raindrop, based on its particular WaveLength.
Classical ElectroMagnetic theory & Special Relativity show that light has [ WaveLength*Frequency = λ*ν = (c) = Speed of Light in vacuum].
Red (scarlet) = Longer WaveLength = Smaller Frequency
Violet (purple) = Shorter WaveLength = Higher Frequency
with: WaveLength (λ) = distance between each crest of the wave; Frequency (ν) = how often a wave's crests pass a given point in space.
We see that the resulting light component's color depends on its particular WaveLength.

Prism

Another phenomena found in nature is the incandescence of magma (under ground) and lava (above ground).
Molten rock at different temperatures will glow in different colors and become darker as it cools.
The eye is remarkably sensative to sublte color differences, and with some practice,
one can estimate the temperature of an object based on its incandescent glow.
From this, we see that light's incandescent color spectrum depends on a material's temperature.

Likewise, blacksmiths have known for centuries that the various metals, particularly iron = "black metal",
when heated for smithing will glow with various colors: the hotter the temperature, the brighter the glow.
These smiths did not measure the temperature of their metals with thermometers, but by the color of the glow.
This heating glow is actually a spectrum of colors, not an individual color as from a prism split.

Later, scientists would connect temperature values to the colors observed.
Here is a chart of colors with their approximate temperatures as observed in glowing metal.
You can see this banding of colors in the sword above, showing the hot spot in the sword.

The above chart shows the heat treat colors for steel by temperature.
These colors were obtained from a 0.40 wt. percent carbon, alloy steel, as seen through a furnace peep hole during average daylight conditions.

Still later, scientists studied the intensities and spectrums of light from a blackbody, an "ideal" incandescent glow, as a function of temperature.
The spectrum generated by such a blackbody due to heat goes from peak intensity invisible InfraRed (IR),ie. "felt as Heat-Warmth"
towards "visible to eye": seen as red,to orange,to yellow,to whitish,to bluish,
and continues to gain more invisible UltraViolet (UV),"felt as damaging Sun-Burn",as the temperature increases.
The visible part of this can be seen in the diagram below, with "Color Temperatures" shown in degrees Kelvin.
In this diagram, the brightness or intensity of the color is not factored in.
It is the "true" color with no other reference (intensity/brightness/etc.) to change the perceived color.

[ Color Temperature in degrees Kelvin ]

By graphing Intensities of light vs. Temperature,and examining the data,one can find a fundamental constant of nature,Planck's Constant (h).


In the experiment simulated below, The temperature of a blackbody is varied with respect to wavelength observed
Slowly increase the Temperature with the slider bar to see the intensity of the spectrum emitted by the blackbody
