brytningsvärde
Brytningsvärde, often abbreviated as BV, is a measure used in optics to quantify the refractive power of a lens. It is defined as the reciprocal of the focal length of the lens in meters. The formula to calculate brytningsvärde is:
where f is the focal length of the lens. A lens with a shorter focal length has
Brytningsvärde is a positive value for converging lenses, which are used to focus light, and a negative
In optical prescriptions, brytningsvärde is used to specify the power of eyeglasses or contact lenses. For
Understanding brytningsvärde is crucial in optics and optometry, as it helps in designing lenses and correcting
