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

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.

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) = 20/4 = 5 meters.

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.

Wavelength is in meters, the frequency is in hertz. period is in seconds and the wave speed is in meters per second.

Convert that to meters. Then divide the speed of light (in meters/second) by the wavelength. The answer will be in 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 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.

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.
