The frequency is 1/5 = 0.2 Hertz. The wavelength is irrelevant in this question.
Speed = (wavelength) times (frequency) = (wavelength) divided by (period) = 30/5 = 6 meters per second
Frequency = (speed) / (wavelength) Period = 1 / (frequency) = (wavelength) / (speed) = (0.01 meter) / (50 mi/sec x 1609.344 meters/mi) = 0.1243 microsecond (rounded)
Frequency = speed/wavelengthPeriod = 1/frequency = wavelength/speed = 0.01/50 = 0.2 millisecond
The wavelength will increase if the period increases.Proof:First define the terms: Wavelength = Lamda (λ), Velocity of propagation = v, frequency = f, period of oscillation = T. Frequency asks "how many waves per unit time (seconds usually)".Period asks "How much time (seconds) does it take for one wave cycle to complete".Also, frequency is inversely proportional to period, so f = 1/T. Also, T = 1/f.(Incidentally, note that as period (T) increases, then frequency (f) gets decreases. Or if frequency increases, then period decreases.)λ = v/forλ = vT. (by replacing f with 1/T)If the frequency decreases, OR/AND the velocity increases, then wavelength corespondingly increases.If the period increases OR/AND the velocity increases, then the wavelength increases.
Period = 1 / (frequency) = 1 / 6th of a second = [166 and 2/3] millisecondsSpeed = (wavelength) x (frequency) = 6 x 3 = [18] meters per second
Speed = (wavelength) times (frequency) = (wavelength) divided by (period) = 30/5 = 6 meters per second
Frequency = speed/wavelengthPeriod = 1/frequency = wavelength/speed = (3,000,000)/(300,000,000) = 0.01 second
The speed of the wave is equal to wavelength x frequency. You can calculate the frequency, in this case, as 1 / period.
Frequency = (speed) / (wavelength) Period = 1 / (frequency) = (wavelength) / (speed) = (0.01 meter) / (50 mi/sec x 1609.344 meters/mi) = 0.1243 microsecond (rounded)
If its wavelength is 50 meters with a period of 6.5 seconds it means it is traveling at 50 meters every 6.5 seconds or 50/6.5 = 7.7 meters/sec.
Wavelength is in meters, the frequency is in hertz. period is in seconds and the wave speed is in meters per second.
If a wave is traveling at 5 meters per second (assuming that is what the question meant) and its wavelength is 20 meters, consider standing beside the wave and watching it pass. As the wave is 20 meters long and it is moving at 5 meters per second, it will take 4 seconds for the full cycle of the wave to pass an observer. That means its frequency is one cycle per 4 seconds. And - surprise! - that's the period of the wave. The period of the wave is 4 seconds.
Period = (1) divided by (frequency) = (wavelength) divided by (speed)Frequency = (1) divided by (period) = (speed) divided by (period)Speed = (wavelength) times (frequency) = (wavelength) divided by (period)Wavelength = (speed) divided by (frequency) = (speed) times (period)
We think of a sound in air. Speed of sound c = 343 meters per second at 20 degrees Celsius or 68 degrees Fahrenheit. The Frequency f = speed of sound c divided by wavelength lambda. Frequency f = 343 / 0.2 = 1715 Hz. The period of time T = 1 / f, that is 1 / 1715 = 0.0005831 seconds = 0.5831 milliseconds. Scroll down to related links and look at "Time period and cycle duration - periodic time to frequency, and frequency to time period".
Frequency = speed/wavelengthPeriod = 1/frequency = wavelength/speed = 0.01/50 = 0.2 millisecond
For any wave:speed = wavelength x frequency So, you must simply calculate the frequency first (it is 1/period), then multiply that by the wavelength.
The main properties of waves are defined below. * Amplitude: the height of the wave, measured in meters. * Wavelength: the distance between adjacent crests, measured in meters. * Period: the time it takes for one complete wave to pass a given point, measured in seconds. * Frequency: the number of complete waves that pass a point in one second, measured in inverse seconds, or Hertz (Hz). * Speed: the horizontal speed of a point on a wave as it propagates, measured in meters / second.
