Wavelength = speed/frequency = 30/10 = 3 meters
(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 metric units for wavelength are meters (m) and for frequency are Hertz (Hz).
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.
If you multiply the wavelength (in meters) and the frequency (in Hertz), you will get the speed of the wave (in meters per second).
(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.
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 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 frequency of a beam of light with a wavelength of 0.2 meters can be calculated using the formula: frequency = speed of light / wavelength. The speed of light is approximately 3.00 x 10^8 meters per second. Plugging this into the formula gives a frequency of 1.5 x 10^9 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.
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 velocity of a wave is calculated using the formula: velocity = frequency × wavelength. Therefore, the velocity of a wave with a frequency of 6 hertz and a wavelength of 2 meters is 12 m/s.
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.
