(4 meters) x (3 per second) = 12 meters per second

331/20 = 16.55 meters.And by the way ... The hertz is not 20. The 'frequency' is 20 hertz.

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.

Just multiply the wavelength (in meters) with the frequency (in Hertz) to get the speed (in m/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.

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.

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.

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.

If you multiply the wavelength (in meters) and the frequency (in Hertz), you will get the speed of the wave (in meters per second).

Divide the speed of light in a vacuum (in meters/second) by the wavelength (which you must convert to meters); that will give you the frequency in hertz. The frequency will be the same for different substances.

You can use the equation v=fw. that is velocity (in meters per second) equals the frequency (in hertz) times the wavelength (in meters). so you can find the velocity of a wave with the frequency and the wavelength.

Wavelength is speed, of light, in this case, divided by frequency. 3 x 108 meters per second divided by 6.82 x 1014 Hertz is 0.4 micrometers.

Wavelength is a length. Hence, the metric unit for it is "meter". Frequency is a reciprocal of time. Hence, the unit for it is "per second", named "Hertz".

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.

Wavelength= 10 mm. Frequency= 5.0 hertz. Speed= 50 mm/second (wavelength x frequency)
