The results of the refraction are used to prescribe eyeglasses or contact lenses that will correct your vision. A refraction is an essential part of your regular eye exam. It will help your doctor identify any ... WebbDiffraction causes the light from the sample to spread out, and this spreading limits our ability to resolve. For transmitted light techniques, the diffraction behavior is determined by the scattering of light from features in the sample. Scattering occurs when light encounters a change in refractive index, such as at the interface of an object. free musical instruments online
