Intensity
Introduction to Intensity In physics, intensity is a measure of the energy flux, or the power per unit area. It is commonly used to describe various phenomena such as light, sound, and electric fields. It quantifies how much energy passes through a specific area in a given time period. Mathematical Definition of Intensity In the…

Airy Disk
Introduction The Airy disk is the bright spot at the center of a pattern that is produced when a plane wave of light is diffracted by a circular aperture. It is named after the British astronomer Sir George Biddell Airy. The pattern consists of a bright central region, or disk, surrounded by a series of…

Transverse Waves
Introduction Transverse waves are waves in which the direction of displacement of the medium’s particles is perpendicular to the direction of the wave propagation. Examples of transverse waves include light waves, radio waves, and waves on a stretched string. This is in contrast to longitudinal waves for which the particle displacement is parallel to the…

Sound Waves
Introduction Sound waves are mechanical waves that propagate through a medium (like air, water, or solids) as a result of vibrations, creating pressure variations that the human ear detects as sound. They are longitudinal waves, where the oscillations occur in the direction of wave propagation. Speed of Sound The speed of sound varies depending on…
