122.6cm/(1/14.6)s or 1789.96cm/s or 58.725722ft/s
speed = frequency x wavelength
Wave speed = wavelength x frequency 4.0 m/s = wavelength x 2.50 Hz 1.6 m = wavelength
Wavelength = 0.4 m Wave speed = 0.4 . 2 = 0.8 m/s
The relationship v = T * λ (speed = frequency * wavelength) is true for all waves. For anything with a constant speed, higher frequency means shorter wavelength.
Speed = frequency x wavelength So required speed = 0.5 * 1 = 0.5 m/s Problem is that the wavelength is not given, but I have taken as 1 m for granted. Hence the answer
speed = frequency x wavelength
Divide the speed by the wavelength. (For any wave, the wavelength times the frequency is equal to the speed of the wave.)
For any wave, the speed of the wave is the product of its frequency and of its wavelength.
Wave speed = wavelength x frequency 4.0 m/s = wavelength x 2.50 Hz 1.6 m = wavelength
Wavelength = 0.4 m Wave speed = 0.4 . 2 = 0.8 m/s
Formula is velocity=frequency X wavelength so Wavelength = 5m
The relationship v = T * λ (speed = frequency * wavelength) is true for all waves. For anything with a constant speed, higher frequency means shorter wavelength.
The speed of sound in fresh water is approx 1,500 metres per second. So wavelength = speed/frequency = 2.94 metres.
Speed = frequency x wavelength So required speed = 0.5 * 1 = 0.5 m/s Problem is that the wavelength is not given, but I have taken as 1 m for granted. Hence the answer
Any wave. Of you have a wave (light, water etc.), it will have a frequency and a wavelength. Multiply these and you get the speed at which the wave is moving.
frequency
You can measure the wavelength without knowing the frequency. This is done by measuring the "nodes" between similar points of a single-frequency continuous wave. All you need is some simple lab equipment. http://www.ted.com/index.php/talks/view/id/237 [the guy measures the wavelength]You can calculate the wavelength as follows: Wavelength times Frequency =Velocity (phase velocity in that medium) So the speed of sound in air is about 344 m/s. If the frequency is 1000 Hz, then the wavelength is 344/1000=.344 m. But in this simple relationship you can't call both wavelength and frequency unknowns. You have to have in hand one or the other.
