Calculating Wave Speed, Frequency and Wavelength Complete each question and show all work. This worksheet is designed to give you some practice using the general wave equation: v=λƒ. (wave speed = wavelength * frequency) 1.) Frequency = 100 Hz Wavelength = 100mm Speed = 2.) Frequency = 200 Hz Wavelength = 200 km Speed = 3.) Frequency = .27 Hz Wavelength = 150 m Speed = 4.) Frequency = 2.7 Hz Wavelength = Speed= 460 m/s 5.) Frequency = Wavelength = 502 m Speed= 1000 m/s 6.) Frequency = Wavelength = 3.26 cm Speed = 14 m/s 7.) Frequency = 97 Hz Wavelength = 13.78 m Speed = 8.) Frequency = 780 Hz Wavelength = 1378 mm

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
