60 mm/s
You get a speed. If the 'Hertz' is the frequency of a particular wave, and the 'meters' is the wavelength of the same wave, then their product is the speed of that wave.
Wavelength = speed/frequency = 30/10 = 3 meters
Frequency = speed / wavelength = 3/0.2 = 15 Hertz
The product of (wavelength x frequency) is the wave's speed.
frequency = speed of wave / wavelength so if speed is constant then frequency varies inversely with wavelength
Wavelength= 10 mm. Frequency= 5.0 hertz. Speed= 50 mm/second (wavelength x frequency)
You get a speed. If the 'Hertz' is the frequency of a particular wave, and the 'meters' is the wavelength of the same wave, then their product is the speed of that wave.
If you multiply the wavelength (in meters) and the frequency (in Hertz), you will get the speed of the wave (in meters per second).
The equation to use in this case is:speed (of the wave) = wavelength x frequency If the frequency is in hertz, and the wavelength is in meters, the speed will be in meters/second.
Wavelength = speed/frequency = 30/10 = 3 meters
1 pulse every 40 microseconds is equal to a frequency of 25,000 hertz
The speed of any wave is the product of wavelength x frequency. In this case, because of the units chosen (meters, and hertz, which is equal to 1/second), the speed will come out in meters/second.
Wavelength = wave speed/frequency Frequency = wave speed/wavelength (Wavelength) x (Frequency) = Wave speed
Frequency = (wave speed) divided by (wavelength)Wavelength = (wave speed) divided by (frequency)Wave speed = (frequency) multiplied by (wavelength)
Divide the speed by the wavelength.
For any wave, frequency x wavelength = speed (of the wave). In this case, convert the kHz to Hz, then divide the speed of light by this frequency. The speed of light should be in meters/second. The answer will be the wavelength in meters.
Wave speed = (frequency) x (wavelength) = (80 per second) x (0.16 meter) = 12.8 meters/second
