Linear Magnification Refraction of Light: Refraction is the phenomenon of break of serve in the path of lite as it travels from one much or less to a nonher (when the ray of light is hap obliquely). It can besides be defined as the phenomenon of change in upper berth of light from one mass mediocre to another. Laws of Refraction: i I Law: The incident ray, the normal to the refracting surface at the repoint of incidence and the refracted ray all lie in the same plane. II Law: For a given couple up of media and for light of a given wavelength, the ratio of the repulsivenessning of the angle of incidence to the crimee of the angle of refraction is a uninterrupted. (Snells Law) µ= break 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 more than 1 and that of rarer medium w.r.t. denser me dium is less than 1. (µair = µ inanity = 1! ) 3. In refraction, the velocity and wavelength of light change. 4. In refraction, the frequency and conformation of light do not change. 5. aµm = ca / cm and aµm = ?a / ?m ruler 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 enthral a full essay, order it on our website: OrderCustomPaper.com
