ACTINOMETER Meaning and
Definition
-
An actinometer is a scientific instrument used to measure the intensity of radiant energy, especially light. It is designed to quantify the amount of radiation received from the sun or other sources. The word "actinometer" originates from the Greek words "aktis" meaning "ray" and "metron" meaning "measure."
Actinometers can be used in various fields such as meteorology, physics, and photography, depending on the specific application. In meteorology, they are used to measure the amount of solar radiation received on the Earth's surface. By determining the intensity of sunlight, actinometers assist in studying weather patterns, evaporation rates, and their impact on climate.
An actinometer typically consists of a glass or metal globe filled with a light-sensitive substance, such as silver chloride, which undergoes a chemical reaction when exposed to radiant energy. The reaction results in a change in color or hue, which can be visually compared to a standardized scale to determine the intensity of the radiation.
In photography, actinometers are used to measure the exposure time required to obtain a desired level of photographic material darkening. This helps photographers determine the appropriate shutter speed or aperture setting for capturing images accurately.
Overall, actinometers play a crucial role in scientific research, providing valuable data on the measurement and understanding of radiant energy, making them an essential tool in various scientific disciplines.

Etymology of ACTINOMETER
The word "actinometer" is derived from the Greek words "aktis", meaning "ray" or "beam", and "metron", meaning "measure". The term was coined in the early 19th century to describe a device used for measuring the intensity of radiation, particularly of sunlight. The "actin-" prefix refers to the measurement of radiation, while "-meter" signifies a device used for measurement.
