Lenses are commonly used in binoculars and telescopes allowing for comprehensive images of distant objects, or in magnifying glasses and microscopes to view small objects, such as microorganisms, which are not visible to the naked eye. Sci. VPH transmission gratings deliver high efficiency, low polarization dependence, and uniform performance over broad bandwidths and large clear aperture. A swimming pool always looks shallower than it really is, because the light coming from the bottom of the pool bends when it comes out at the surface due to refraction of light. Among them … The refractive index of a material varies with the wavelength incident upon it, which results in a phenomenon called dispersion where the different wavelengths of light refract by different amounts and create a rainbow effect. As a result we see the fish but that is not exactly on that position where we . A refractometer characterizes fluids based on their refractive index –the refraction occurs due to the change in the speed of light as it travels through a material of one density to one of different density. Total internal reflection refers to the completereflection of a ray of light within a given medium from the surroundingsurface. As a result, the pickles in the jar appear bigger than they really are. Recently, metamaterials that display negative refractive index – a property not found in any known naturally occurring material – have drawn significant scientific interest, underscoring the remarkable potential of metamaterials to facilitate new developments in electromagnetism.

Camera 2. - 13185192 Answer: Refraction is a phenomenon that occurs when waves passing from one transparent medium to another bend at the boundary between the two shows how to the wavelength in a given medium, λnλn, is related to the wavelength in a vacuum, λλ, and the refractive index, n, of the medium. The refractive index of a material is one of the most important optical parameters. "The Applications of Refraction". It consists of a large number of equally spaced parallel slits.” Its working principle is based on the phenomenon of diffraction.The space between lines acts as slits and these slits diffract the light waves thereby producing a large number of beams that interfere in such a way to produce spectra. It is mostly applied for identify a particular substance, confirm its purity, or measure. Gaseous dielectric in capacitor. The refractive index increases with decrease in the chain length whereas a double bond elevates the refractive index [46]. It is used to calculate the focusing power of lenses, and the dispersive power of prisms. As a result of the difference in refractive index, the ray will be bent towards the surface. Join now.
