IPC Notes The Nature of Waves

A wave is a repeating disturbance or movement that transfers energy through matter or space. ex) light, sound & radio

The Nature of Waves A medium is any material that a wave transfers energy through. ex) water is the medium for ocean waves

2 Types of Waves A transverse wave occurs when the particle movement is at right angles to the direction of the wave. ex) water waves

2 Types of Waves A compressional wave occurs when the particle movement is in the same direction as the wave. ex) sound waves

Wave Properties wavelength – the distance between one point on a wave and the nearest point just like it

Wave Properties frequency – the number of wavelengths that pass a given point each second

Wave Properties crest – the highest point of a wave

Wave Properties trough – the lowest point of a wave

Wave Properties amplitude – the measure of the energy of a wave

Wave Diagrams Draw a transverse wave diagram and label the following parts: crest, trough, wavelength, amplitude & rest position

Compressional Waves compression – the part of a compressional wave where the particles are close together

Compressional Waves rarefaction – the part of a compressional wave where the particles are far apart

Compressional Waves wavelength – includes one complete compression and one complete rarefaction
