If a wave has a wavelength of 2 m and a frequency of 20 Hz what is the speed of the wave?
it gets divided by 10; frequency = speed/wavelength; wavelength = speed/frequency
That also depends on the speed of the wave. Use the formula speed = wavelength x frequency, or wavelength = speed / frequency. In the case of an electromagnetic wave in a vacuum, use 300,000,000 m/s for the speed.
Wavelength= 10 mm. Frequency= 5.0 hertz. Speed= 50 mm/second (wavelength x frequency)
Convert the cm to meters, to have compatible units. Then use the fact that the frequency times the wavelength is equal to the speed of the wave. In this case, you can divide the speed by the wavelength, to get the frequency.
wl= v/fwhere wl = wavelength (m)v = velocity (m/s)f = frequency (Hz)there forwhen wl = 1 mand v = 10 m/sf = v/wlf= 10/1f= 10 hz(For wavelength traditional character is lambda)
it gets divided by 10; frequency = speed/wavelength; wavelength = speed/frequency
Wavelength = (speed) divided by (frequency) = 10/0.5 = 20
That also depends on the speed of the wave. Use the formula speed = wavelength x frequency, or wavelength = speed / frequency. In the case of an electromagnetic wave in a vacuum, use 300,000,000 m/s for the speed.
Wavelength= 10 mm. Frequency= 5.0 hertz. Speed= 50 mm/second (wavelength x frequency)
Frequency = (speed)/(wavelength) = 10/20 = 1/2
Frequency = (speed)/(wavelength) = 20/2 = 10 Hz
Convert the cm to meters, to have compatible units. Then use the fact that the frequency times the wavelength is equal to the speed of the wave. In this case, you can divide the speed by the wavelength, to get the frequency.
Wavelength = speed/frequency = 30/10 = 3 meters
Wavelength = (speed) / (frequency) = (5,000) / (10) = 500 meters = 0.5 km.
Frequency = speed/wavelengthPeriod = 1/frequency = wavelength/speed = 0.01/50 = 0.2 millisecond
wl= v/fwhere wl = wavelength (m)v = velocity (m/s)f = frequency (Hz)there forwhen wl = 1 mand v = 10 m/sf = v/wlf= 10/1f= 10 hz(For wavelength traditional character is lambda)
We don't know.Every wave has wavelength, frequency, and speed. In order to find any one of them,we need to know the other two.
