Ray Optics and Optical Instruments Class 12 Notes Chapter 9
WebWave optics, also called Physical optics, deals with the study of various phenomena such as polarization, diffraction, interference and other occurrences where ray approximation of geometric optics cannot be done. Thus, the section of optics that deals with the behaviour of light and its wave characteristics is said to be wave optics. WebSolution : Fresnel’s distance (ZF) is the distance for which the ray optics is a good approximation. It is given by the relation, ZF=a2λ. Where, Aperture width, a = 4 mm = 4 × 10 -3 m. Wavelength of light, λ = 400 nm = 400 × 10 -9 m. Therefore, the distance for which the ray optics is a good approximation is 40 m. citizens nb cheboygan
