The two sources of light in Young's experiment could be two different light bulbs. For Young's equation to be geometrically valid, the distance from the sources to the screen must be much greater than the slit separation distance. For Young's equation to be geometrically valid, the wavelength...
For example, the show I am working on now I have a bunch of Opti Tri Pars and was color matching them to R67 which is Light Sky Blue. I can tell you right now, my mix to match it had a slight hint of red in it to cut the saturation down because it was too cyan and not re...
LEDs bulbs can produce a wider range of color, from warm (2700K) to cool daylight tones (5000K). To match the light quality of an incandescent bulb, choose an LED with similar color temperature. See chart below:
When a light has a CRI of 100, it means that there is no difference in color rendition between the light and the reference light (the sun). Likewise, a CRI of 75 means that the light bulb renders a 75% replication of the visible colors that the sun shows, given that both lights hav...
After normalizing the X, Y, and Z from the CIE XYZ tristimulus values, one can derive the final x,y values which define the color of a particular light (irrespective of its luminance) on the chromaticity chart: x = X/(X + Y + Z) ...
It is this value that is used to calculate the effective light output of light bulbs in lumens. The chromaticities x and y indicate the hue and saturation of the color. Often the color is described in terms of [x, y, Y] because of the ease of interpretation. Other color coordinate ...
Type of lighting:Artificial lights (light bulbs) can influence how others experience your eye color. The brightness of light reflecting from your iris will either increase or soften your iris’s appearance. Morning vs. Afternoon:The sun’s light may be more intense in the morning, which means...
the chart below, light during the day changes from warm at sunrise/sunset to cool at mid-day. Other lights are different colors. Mercury vapor lamps produce a bluish-green light. High pressure sodium street lamps produce an orange-yellow glow. Fluorescent bulbs can be green, warm, or white...

chart. For example, a pink color can be formed by a combination of blue, red, and green. The relative brightnesses of the colored lights are adjusted to provide 100% red, 50% blue, and just a little (25%) green. The absolute brightness of the pink color can be adjusted by adjusting...
