It's 2, with same length-unit as the one in the speed
10 m
Frequency = speed/wavelengthPeriod = 1/frequency = wavelength/speed = 0.01/50 = 0.2 millisecond
There need not be any wavelength if the body is moving laterally and continues to do so.
Frequency = (speed) / (wavelength) Period = 1 / (frequency) = (wavelength) / (speed) = (0.01 meter) / (50 mi/sec x 1609.344 meters/mi) = 0.1243 microsecond (rounded)
wavelength = speed / frequency Wavelength should be expressed in meters (m), speed in meters per second (m/s), and frequency in hertz (Hz). I assume by "ms" in the question you actually mean "m/s" since the former is "milliseconds" (a measure of time) and the later is "meters per second" (a measure of speed). 1000 / 50 = 20 meters
Wave speed = (frequency) x (wavelength) = (50) x (20) = 1,000 meters.
10 m
10 m
50 / 2.5 = 20, same units as numerator of velocity
Frequency = Velocity / Wavelength = 100 m/s / 20 m = 5 s-1 or 5 Hz.
Wavelength= 10 mm. Frequency= 5.0 hertz. Speed= 50 mm/second (wavelength x frequency)
A Frequency of 50 Hertz has a Wavelength of 5.9958e+8 Centimeters 1.9671e+7 Feet 5.9958e+6 Meters
Frequency = speed/wavelengthPeriod = 1/frequency = wavelength/speed = 0.01/50 = 0.2 millisecond
It just is. Sound behaves like a wave, and the pitch of the sound affects the wavelength. And wavelength is directly related to the frequency. A high pitched sound has a a shorter wavelength and a higher frequency than a low-pitched sound.
assuming that the electrons travel very close to C (the speed of light, i.e. 299 792 458 m / s) then simply using:Wavelength = Velocity / frequency it is given: Wavelength @50Hz= (299 792 458 (m*sec-1))/(50 (sec-1))=599584917 m = ~6000km (remember that once the distance gets to factors of 25%, 50%, 100%, 125% ... of the wavelength, funny stuff happens to your transmission line due to the equivalent impedance at the receiving point!)
The speed of a wave is equal to the product of wavelength x frequency. Just convert everything to standard units (wavelength to meters, frequency to hertz), multiply both, and you'll get the result, also in standard units (meters / second).
it decrease the wave length
