\"\"<\/p>\n

Example 10.2:<\/span> A wave moves on a slinky with frequency of 4Hz and wavelength of 0.4 m. What is the speed of the wave?<\/strong>
\nSolution:<\/strong><\/span><\/p>\n

Given that, f = 4 Hz, \u03bb = 0.4 m
\nWave speed\u00a0 v = f \u03bb<\/p>\n

v = (4 Hz) (0.4 m)<\/p>\n

v = 1.6 m s-1<\/sup><\/p>\n

Example 10.3:<\/span> A student performs an experiment with waves in water. The student measures the wavelength of a wave to be 10 cm. By using a stopwatch and observing the oscillations <\/strong>of a floating ball, the student measures a frequency of 2 Hz. If the student starts a wave in one part of a tank of water, how long will it take the wave to reach the opposite side of the <\/strong>tank 2 m away?<\/strong>
\nSolution:<\/strong><\/span>
\n(1) We are given the frequency, wavelength, and distance.
\n(2) We have to calculate the time, the wave takes to move a
\ndistance of 2 m.
\n(3) The relationship between frequency, wavelength, and speed is
\nv = f \u03bb. The relationship between time, speed, and distance is
\nv = d \/t
\n(4) Rearrange the speed formula to solve for the time: t = d \/ v
\nThe speed of the wave is the frequency times the wavelength.<\/p>\n

v = f \u03bb = (2 Hz)(0.1 m) = 0.2 m s-1<\/sup> .
\nUse this value to calculate the time:<\/p>\n

t = 2 m\/0.2 m s-1<\/sup> = 10s<\/p>\n
