is defined as temperature (i.e., the particles surrounding your thermometer). Your temperature reading would be absolute zero if there were no particle’s surrounding your thermometer (because you are in a perfect vacuum).However, we know from the third law of thermodynamics that zero Kelvin ...

What does it mean when you see a shelf cloud? Shelf clouds themselves are harmless but can be an indicator of strong storms. They are the leading edge of these storms. Shelf clouds can even form before a derecho strikes. If you see a shelf cloud coming your away, it probably meansyou ...
It should be noted that a CRI of 100 does not mean perfect lighting, nor are the colors perfectly accurate. The CRI value is an expression of how close the observed light is to the reference light. If the reference light doesn’t show good colors, then a CRI of 100 wouldn’t be pref...
A critical area often considered when selecting a SAD lamp is blue or white color.The color temperature of light refers to its "warmth" or "coolness."This is measured in kelvin (K). Warmer lights, around 1,000 K, promote comfort and have a calming effect. Cooler lights, around 10,000...
This tells you that different camera models, even if they’re from the same manufacturer, affect the final look of the image. The reason for this lies in the software used for RAW processing. What does that mean for you if you use different cameras? It means that if you want to copy ...
Kelvin Helmholtz Wavesare perhaps the rarest cloud formation of all. Rumored to be the inspiration for Van Gogh's masterpiece “Starry Night”, they are incredibly distinctive. They are mainly associated with cirrus, altocumulus, and stratus clouds over 5,000m. ...
Light bulbs have a color temperature listed using the Kelvin Color Temperature Scale. The lower the number, the warmer and more red the light; the higher the number, the cooler and more blue the light. Candle flames are 1,900K. They are very warm and cast a reddish/yellow light. Stand...
