Wavelength= 10 mm.
Frequency= 5.0 hertz.
Speed= 50 mm/second (wavelength x frequency)
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.
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)
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.
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.
If you multiply the wavelength (in meters) and the frequency (in Hertz), you will get the speed of the wave (in meters per 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)
60 mm/s
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
