The formula to calculate the Color Temperature (T) is:
\[ T = \frac{2 \times 10^6}{\lambda} \]
Where:
Let's say the wavelength (\( \lambda \)) is 500 nm. Using the formula:
\[ T = \frac{2 \times 10^6}{500} \]
We get:
\[ T = 4000 \text{ K} \]
So, the Color Temperature (\( T \)) is 4000 K.
Color temperature is a characteristic of visible light that describes the hue of the light source. It is measured in Kelvin (K) and is used to describe the warmth or coolness of a light source. Lower color temperatures (around 2000-3000K) produce a warm, yellowish light, while higher color temperatures (above 5000K) produce a cool, bluish light. Color temperature is an important factor in photography, videography, and lighting design, as it affects the mood and appearance of a scene.
Definition: Color temperature is a measure of the color of light emitted by a light source, expressed in degrees Kelvin (K).
Formula: \( T = \frac{hc}{k \lambda} \)
Example: \( T = \frac{6.626 \times 10^{-34} \times 3 \times 10^8}{1.38 \times 10^{-23} \times 500 \times 10^{-9}} \)
Definition: Correlated color temperature (CCT) is a measure of the color appearance of a light source, indicating whether it appears more yellow/golden or blue.
Formula: \( CCT = 437 \times \left( \frac{1}{x} - 1 \right) + 360 \times \left( \frac{1}{y} - 1 \right) \)
Example: \( CCT = 437 \times \left( \frac{1}{0.33} - 1 \right) + 360 \times \left( \frac{1}{0.34} - 1 \right) \)
