331/20 = 16.55 meters.
And by the way ... The hertz is not 20. The 'frequency' is 20 hertz.
Wavelength = speed/frequency = 30/10 = 3 meters
(4 meters) x (3 per second) = 12 meters per second
Wavelength x frequency = speed of the wave, so wavelength = speed / frequency. In SI units, wavelength (in meters) = speed (in meters/second) / frequency (in Hertz). If you are talking about electromagnetic waves in avacuum, use 300,000,000 m/s for the speed.
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.
Just multiply the wavelength (in meters) with the frequency (in Hertz) to get the speed (in m/s).
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 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.
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
Just divide the speed of light (in meters/second) by the frequency (in hertz) - that will give you the wavelength (in meters). You can then convert that to nm.
(4 meters) x (3 per second) = 12 meters per second
Wavelength x frequency = speed of the wave, so wavelength = speed / frequency. In SI units, wavelength (in meters) = speed (in meters/second) / frequency (in Hertz). If you are talking about electromagnetic waves in avacuum, use 300,000,000 m/s for the speed.
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.
500 hertz
Just use the relationship: speed (of the wave) = frequency x wavelength. If the frequency is in hertz (cycles/second), and the wavelength in meters, then of course the speed will be in meters/second.
Depends on what the speed of the wave is. The wavelength is equal to the speed of the wave divided by its frequency. For light in a vaccum, for instance, the speed is c, or about 3.00 x 10e8 meters/second. If the frequency was in Hertz (cycles/second), then the wavelength would be 448,000 meters. So, this probably is a light frequency. If it were the sound at sea level, the speed is 340 meters/second, so the resulting wavelength would be 0.507 meters. The sound would be nearly an "E".
That would also depend on the speed. Note that sound can go at quite different speeds, depending on the medium and the temperature. Use the formula speed (of sound) = frequency x wavelength. Solving for wavelength: wavelength = speed / frequency. If the speed is in meters / second, and the frequency in Hertz, then the wavelength will be in meters.
