IB DP Physics: HL复习笔记4.5.4 Harmonics
Harmonics Stationary waves can have different wave patterns, known as harmonics These depend on the frequency of the vibration and the boundary conditions (i.e. fixed and/or free ends) The harmonic...
IB DP Physics: HL复习笔记4.5.3 Boundary Conditions for Standing Waves
Boundary Conditions Stationary waves can form on strings or in pipes In both cases, progressive waves travel in a medium (i.e. the string or air) and superimpose with their reflections The number o...
IB DP Physics: HL复习笔记4.5.2 Nodes & Antinodes
Nodes & Antinodes A standing wave is made up nodes and antinodes Nodes are locations of zero amplitude and they are separated by half a wavelength (λ/2) Antinodes are locations of maximum ampli...
IB DP Physics: HL复习笔记4.5.1 The Nature of Standing Waves
The Nature of Standing Waves Standing waves are produced by the amplitude travelling in opposite directions This is usually achieved when a travelling wave superimposes its reflection The superposi...
