  7. COMMUNICATIONS • Elements of communication • How does communication travel? • Communication through sound waves mortongroveil.org

  8. Elements of Communication transmitter receiver www.tecno12-18.com Message: information sent in a communication channel

  9. How does communication travel? Sound waves cables zdnet.com isvr.soton.ac.uk

  10. Communication through sound waves nanobioart.com

  11. 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

  12. Representation of sound waves • They are usually represented as wavy lines www.tecno12-18.com

  13. 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

  14. 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

  15. FREQUENCY • Frequency (f): number of waves per second • Mesure of frequency: Hertz(Hz) mendonphysics2007p9.blogspot.com

  16. Relationship between Wavelength and Frequency • Short wavelength high frequency. • Long wavelenghtlow frequency.
