Wave Optics

This topic explores the wavefront and its different types based on the shapes. It discusses the statements for the Huygens’ principle and its steps of construction. It also briefs on the behaviour of plane wavefront in reflection and refraction.

In this topic, we will study the principle of superposition and the interference of light waves with the help of a figure. It explains the conditions for the constructive and destructive interferences and sustained interference of light waves.

This topic teaches us the interference of light through a double slit with the help of Young’s double slit experiment. We will also study the interference pattern, the formation of fringes and the expression for the fringe-width.

In this topic, we will learn about the phenomenon of diffraction of all types of waves such as sound wave, light wave or water wave. Diffraction by a single slit is also explained here.

This topic deals with concepts and formulas related to the polarisation by scattering and reflection. The process of polarisation is explained with an experimental activity.
