Refractive power definition
In optics, optical power (also referred to as dioptric power, refractive power, focusing power, or convergence power) is the degree to which a lens, mirror, or other optical system converges or diverges light. It is equal to the reciprocal of the focal length of the device: P = 1/f. High optical power corresponds to short focal length. The SI unit for optical power is the inverse metre (m ), which is co… WebAcoustic refraction - Filipino translation, definition, meaning, synonyms, pronunciation, transcription, antonyms, examples.
