General Wave Properties

Waves and Energy Transfer A wave is a disturbance that transfers energy from one place to another without transferring matter . As a wave travels through a…
Transverse & Longitudinal Waves

Transverse Waves In a transverse wave, the direction of vibration of the particles is at right angles (perpendicular) to the direction in which the wave travels…
Wave Behaviour

Reflection, Refraction and Diffraction When a wave meets a barrier, or crosses a boundary into a different medium, it can change direction. Waves can undergo…
Light

Light is a transverse electromagnetic wave that travels at 3 × 10^8 m/s in a vacuum, and obeys the same reflection, refraction and diffraction rules as other…
Thin Lenses

Converging and Diverging Lenses Action on a Parallel Beam of Light A converging (convex) lens is thicker in the middle than at its edges; a parallel beam of…
Electromagnetic Spectrum

Properties of Electromagnetic Waves Electromagnetic (EM) waves are transverse waves - oscillating electric and magnetic fields, perpendicular to each other and…
Sound Waves

Production and Transmission of Sound Sound is produced by a vibrating source , such as a tuning fork, a loudspeaker cone, a guitar string, or vocal cords The…
