Unit I Wave Optics Interference : Introduction to electromagnetic waves and electromagnetic spectrum. Interference in thin film of uniform thickness (with derivation). Interference in thin film wedge shape (qualitative). Applications of interference: testing optical flatness, anti-reflection coating. Diffraction : Diffraction of light. Diffraction at a single slit, conditions for principal maxima and minima, diffraction pattern. Diffraction grating, conditions for principal maxima and minima starting from resultant amplitude equations, diffraction pattern. Rayleigh’s criterion for resolution, resolving power of telescope and grating. Polarization : Polarization of light, Malus law. Double refraction, Huygen’s theory of double refraction Applications of polarization: LCD. (Chapters - 1, 2, 3) Unit II Laser and Optic Fibre Laser : Basics of laser and its mechanism, characteristics of laser. Semiconductor laser: Single Hetro-junction laser. Gas laser : laser. Applications of lasers: Holography, IT, industrial, medical. Optic Fiber : Introduction, parameters: Acceptance Angle, Acceptance Cone, Numerical Aperture.
