What does /SR mean in UNIT MEASURES
"Per Steridian" (SR) is a mathematical term used to express the amount of something per unit solid angle. A solid angle is a three-dimensional cone-shaped region of space, and the unit solid angle is called a steradian.
/SR meaning in Unit Measures in Miscellaneous
/SR mostly used in an acronym Unit Measures in Category Miscellaneous that means Per Steridian
Shorthand: /SR,
Full Form: Per Steridian
For more information of "Per Steridian", see the section below.
- Per Steridian (/SR) is a mathematical and scientific term used to describe the solid angle subtended by a cone or a spherical surface area. It is a measure of the angle formed by two lines, or rays, emanating from a common point and intersecting a surface. The symbol '/SR' is used to denote 'per steradian'.
What does /SR Stand for?
- The abbreviation /SR stands for 'Per Steridian', which means 'per unit solid angle'. It is a dimensionless quantity expressed in steradians (sr).
Calculating /SR
- The solid angle (Ω) subtended by a cone or a spherical surface area is calculated as the ratio of the intercepted surface area (A) to the square of the distance (r) from the point of intersection to the intercepted surface area:
Ω = A / r² - The resulting solid angle is measured in steradians (sr).
Applications of /SR
- /SR is used in various fields, including:
- Optics: To calculate the intensity of light sources and the solid angle of lenses.
- Radiation physics: To describe the distribution of radiation from sources and the solid angle of radiation detectors.
- Astronomy: To measure the angular size of celestial objects and the solid angle of telescopes.
