Wave Speed on a Stretched String The speed of a wave travelling along a string with two fixed ends is given by: Where: T = tension in the string (N) μ = mass per unit length of the string (kg m–1) ...
Stationary Waves Stationary waves, or standing waves, are produced by the superposition of two waves of the same frequency and amplitude travelling in opposite directions This is usually achieved b...
Phase & Path Difference Waves are said to be coherent if they have: The same frequency A constant phase difference Phase Difference Two points on a wave, or on different waves, are in ph...
Interference & Superposition of Waves Interference occurs whenever two or more waves combine to produce a resultant wave with a new amplitude Superposition literally means to be positioned over...
Core Practical 6: Investigating the Speed of Sound Aim of the Experiment To measure the speed of sound in air using an oscilloscope and a signal generator Variables Independent variable = Distance ...
Graphs of Transverse & Longitudinal Waves Graphs of Transverse Waves There are two common graphs transverse waves; Displacement against distance Displacement against time These are: Similar bec...
Transverse Waves Transverse Waves A transverse wave is one where the particles oscillate perpendicular to the direction of the Propagation of the wave Direction of energy transfer Transverse waves ...
