© Oxford University Press 2011 IP The wave equation The wave equation The speed of a wave depends on its frequency and its wavelength. They are related. If the wave speed is called v, the frequency f and the wavelength, then: Wave speed metres/second (m/s) = = frequency hertz (Hz) wavelength metres (m) v = f
© Oxford University Press 2011 IP The wave equation Dylan is standing on the end of a pier. He measures the water waves going past him. The wavelength of each wave is 1.3 m. He counts 2 waves every second. Find the wave speed. Wave speed = frequency wavelength v = 2 Hz 1.3 m v = 2 1.3 m/s v = 2.6 m/s
© Oxford University Press 2011 IP The wave equation Find the speed of a wave whose wavelength is 40 m and frequency is 100 Hz. Wave speed = frequency wavelength v = 100 Hz 40 m v = 100 40 m/s v = 4000 m/s

© Oxford University Press 2011 IP The wave equation A speaker produces sound at a frequency of 6.6 kHz. The speed of sound is 330 m/s. Calculate the wavelength. wavelength = = = 0.05 m = 5 cm wave speed frequency 330 m/s 6600 Hz
1.The speed of a wave with a frequency of 10kHz and a wavelength of 2m. v = f x λ v = 10,000 x 2 v = 20,000m/s.
Calculating Wave Speed. The Speed of Waves The speed that a wave travels at depends on two things, the frequency of the wave f (how many in a second)
Calculating Wave Speed. Wave Speed v fλ Practice Problem #1 What is the speed of a sound wave that has a wavelength of 2 m and a frequency of Hz?
PROPERTIES OF WAVES. Waves A wave is a means of transferring energy and information from one point to another without there being any transfer of matter.
The faster the end of the rope is ‘waggled’, the shorter the wavelength produced The wave equation.
Waves Wave speed = Frequency x Wavelength Metres/second m/s Hertz Hz Metres m What is the wave speed when the frequency of a wave is 2.5Hz and the wavelength.
There is a relationship between frequency (f), speed (v) and wavelength (λ) If the source vibrates faster (greater frequency), the wavelength changes.
Waves L.O. To describe the transfer of energy by waves To use the Keywords associated with waves To calculate any of the three quantities associated with.
What is the wavelength? What is the amplitude?.
Waves can also be reflective and refractive Waves can bounce off of something after striking it. That is a reflection. Sound and light waves can equally.
