A refractometer is an instrument that measures the refractive index of a substance, or, in layman’s terms, the degree that light, passing through a solution, is bent. By measuring the difference between the angle of the light ...
WebIt is calculated as follows: D = 1/ f where f is the focal distance of the lens. Larger focal length lenses have less optical power. In SI, optical power is measured in reciprocal meter (m⁻¹). This unit is usually called the dioptre or diopter. For example, a 2-diopter lens can focus parallel rays of light at ½ meter. Webreff = (4/3) re and use this to create a simple formula for determining the range to the radio horizon: d = (2zreff)1/2 This is called the 4/3rds earth radius assumption and it is often used by engineers to estimate radar ranges. This is based on a standard atmosphere.
