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).
Wavelength = speed/frequency = 30/10 = 3 meters
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.
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.

You can calculate frequency from wavelength using the equation: frequency = speed of light / wavelength. The speed of light in a vacuum is approximately 3.00 x 10^8 meters per second. By dividing this speed by the wavelength of light in meters, you can determine the frequency in hertz.
Just multiply the wavelength (in meters) with the frequency (in Hertz) to get the speed (in m/s).
The wavelength of blue light with a frequency of 6.82x1014 Hertz is approximately 440 nanometers. This is calculated using the formula: wavelength = speed of light / frequency.
The wavelength of a wave with a frequency of 1 hertz is 1 meter. Wavelength is the distance between two consecutive peaks or troughs of a wave, and it is inversely proportional to the frequency of the wave.
The speed of a wave can be calculated using the formula v = f * λ, where v is the speed, f is the frequency, and λ is the wavelength. Plugging in the values given (f = 250 Hz and λ = 1.3 m) into the formula gives a speed of 325 m/s.
