Superposition

The Principle of Superposition When two or more waves travel through the same medium simultaneously, their effects combine. This can occur with waves travelling…

Stationary Sound Waves in Pipes Sound waves travelling inside a tube (pipe) reflect from the ends, creating stationary waves through superposition. The pressure…

What is Diffraction? Waves travel in straight lines when unobstructed. When waves pass the edge of an obstacle or pass through a gap between obstacles, they…

What is Interference? When two or more waves overlap in the same region of space, they combine according to the principle of superposition. The resulting…

What is a Diffraction Grating? A diffraction grating consists of a large number of equally spaced parallel slits (or lines). When light passes through, it…
