WebIn geometrical optics, vergence describes the curvature of optical wavefronts. [1] Vergence is defined as. where n is the medium's refractive index and r is the distance from the point source to the wavefront. Vergence is measured in units of dioptres (D) which are equivalent to m −1. [1] This describes the vergence in terms of optical power. WebThis is achieved due to refraction at both surfaces of the lens because light travels more slowly in glass than air. Diverging Lens.
