Properties of Traveling Waves IB PHYSICS | WAVES - SOUND What is a Wave? Two Types of Waves Particles move perpendicular to the wave’s motion Particles move parallel to the wave’s motion Examples: • Ripples in a pond • Light Waves Examples: • Sound Waves • Earthquake Waves Properties of a Wave Properties of a Wave Property Symbol Unit Amplitude Wavelength distance How Many Waves? Wavelength is related to frequency Longer wavelength _________ frequency Shorter wavelength _________ frequency Lower Higher Wave Speed Equation Speed = Frequency × Wavelength Sy m b o ls U n it s = × = × Read a Wave #1 # of Waves Period Amplitude Frequency 1 2 3 3 2 1 0 M et er s Seconds 0 1 2 3 4 5 6 7 8 9 10 11 12 𝑓 = 1 𝑇 𝑇 = 1 𝑓 Read a Wave #2 1 2 3 3 2 1 0 M et er s Seconds 0 1 2 3 4 5 6 7 8 9 10 11 # of Waves Period Amplitude Frequency 𝑓 = 1 𝑇 𝑇 = 1 𝑓 One Final Question… The crests of waves passing into a harbor are 2.1 m apart and have an amplitude of 60 cm. 12 waves pass an observer every minute. What is their frequency? What is their speed?
