Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the measurement unit?Color temperature of light
2. What is the SI equivalent term?Reciprocal megakelvin (MK−1), also known as mirek
3. How do you calculate a mired?You divide one million by the light’s temperature in Kelvins. The formula is M = 1,000,000 ÷ T, where T is the temperature in K.
4. Why do photographers use mireds?Mireds let photographers adjust light so pictures look natural. They show how much a light’s color will change, making it easier to match different lights.

Mired: A unit measuring color temperature, calculated as 1,000,000 divided by Kelvins, reflecting perceptual changes.
Color Temperature: The spectral distribution of light, typically described by the Kelvin scale, indicating its perceived warmth or coolness.
Kelvin (K): The base unit of thermodynamic temperature, used here to quantify the color temperature of light sources.
Reciprocal: The multiplicative inverse of a number; for temperature T, it is 1/T. Mireds use 1,000,000/T.
