Linear Magnification Refraction of Light: Refraction is the phenomenon of miscue in the path of lite as it travels from one modal(a) to a nonher (when the ray of light is hap obliquely). It can in like manner be defined as the phenomenon of change in advance of light from one mass moderate to another. Laws of Refraction: i I Law: The incident ray, the normal to the refracting surface at the repoint of relative incidence and the refracted ray all lie in the sa me plane. II Law: For a given correspond of media and for light of a given wavelength, the ratio of the repulsivenessning of the angle of incidence to the delinquencye of the angle of refraction is a uninterrupted. (Snells Law) µ= transgress i sin r Rarer N Denser r r N µ i Rarer (The constant µ is called refractive index of the medium, i is the angle of incidence and r is the angle of refraction.) TIPS: 1.

µ of optically rarer medium is lower and that of a denser medium is higher. 2. µ of denser medium w.r.t. rarer medium is much than 1 and that of rarer medium w.r.t. denser medium is less than 1. (µair = µ mindlessness = 1) 3. In refrac tion, the velocity and wavelength of light c! hange. 4. In refraction, the frequency and frame of light do not change. 5. aµm = ca / cm and aµm = ?a / ?m dogma of Reversibility of Light: a µb = a µb sin i bµa = sin r x bµa = 1 or a µb sin r Rarer (a) i sin i = 1 / bµa If a ray of light, later on suffering any number of reflections and/or refractions has...If you want to charm a full essay, order it on our website: OrderEssay.net
