What’s a sound wave? • A soundwave is a disturbance which travels through space . • The waves carry signals from one place to another jdsage.com jasonmar.com adsoftheworld.com
Representation of sound waves • They are usually represented as wavy lines www.tecno12-18.com
Parts of a sound wave crest axis trough Axis: the line running through the middle of the wave patern. Crest: the top part of a wave Trough: the lowest part of a wave sci-toys.com
Characteristics of a sound wave Wavelength (λ) CYCLE`:Part of a wave that is continuously repeated amplitude(A) www.tecno12-18.com Amplitude (A):The distance from the axis to the top of the crest or the bottom of the trough www.tecno12-18.com Wavelenght(λ):Distance between two adjoining crests
FREQUENCY • Frequency (f): number of waves per second • Mesure of frequency: Hertz(Hz) mendonphysics2007p9.blogspot.com
Relationship between Wavelength and Frequency • Short wavelength high frequency. • Long wavelenghtlow frequency.
