Click on words

The astronomer used photometry to determine the luminosity of distant stars by measuring their light intensity.

In the laboratory, researchers applied photometry techniques to analyze the color spectrum of light emitted by various chemical reactions.

What is "photometry"?

Photometry is the science of measuring the intensity of light. It involves determining how much light is emitted, reflected, or transmitted by an object or source. This process is important in various fields, including photography, astronomy, and lighting design, to ensure accurate lighting conditions and quality. Photometry helps in evaluating how bright a light source is and how it will appear in different settings.

캐럿

a unit to measure the purity of gold, the purest gold being 24 karats

What is a "karat"?

A karat is a unit of measurement used to denote the purity of gold, with one karat being equal to 1/24th of the whole. Therefore, 24-karat gold is considered to be pure gold. The higher the karat number, the higher the percentage of gold in the item. For example, 18-karat gold contains 75% gold, while 14-karat gold contains 58.3% gold. Karat is also used as a term to describe the weight of gemstones, with one karat equal to 0.2 grams. The term "carat" is sometimes used interchangeably with "karat," but carat is generally used to describe the weight of diamonds and other gemstones, while karat is used to describe the purity of gold.
