A wave has a period of 4.0 seconds the frequency of this wave is?

frequecy and period have an indirect relationship F=1/4s =.25 Hertz


The period of a mechanical wave is 4 seconds What is the frequency of the wave?

1/4 or .25 F hope this helps


What is the frequency of a wave that has a period of 2.5 seconds?

The speed of the wave c = frequency f times wavelength lambda. c = 25 times 5 = 125 m/s, whatever that medium on what planet may be. Some formulas: Scroll down to related links and look at "Wavelength".


25 waves in 2 seconds what is the frequency?

50


What does it mean to say that the frequency of a wave is 25 hertz?

It means the the wave has a speed of 25 vibrations per second


What is the wavelength of a wave with a frequency of 5 Hz and a speed of 25 M's?

Simply using the relation wavelength = velocity / frequency So required wavelength = 25/5 = 5 m


If 25 waves are produced in 20 seconds what will be the frequecy?

25 waves are produced in 20 seconds , so 25 ÷ 20 = 1.25 waves in 1 second ... so the Frequency is 1.25 Hz


If a wave travels down the length of a 25-meter rope in 5.0 seconds The speed of the wave is?

5 metres per second. V (velocity) = Distance/Time = 25/5 = 5


What is the frequency of a wave with a wavelength of 25 meter and a speed of 37.5 meters per second?

Freq = Speed/Wavelength = 37.5/25 Hz = 1.5 Hz


What is a wave with a frequency of 10 hertz that travels a speed of 25 meters per second?

The speed (v) of a wave = frequency (f) x wavelength (λ); v = ƒ• λ.To solve for wavelength when you have speed and frequency, divide speed by the frequency; λ = v/ƒ .λ = v/ƒ = 25m/s x 10Hz = 250m


What are the frequency and duty cycle when a periodic signal waveform has a pulse width of 25s and a period of 150s?

Frequency: F=1/P =1/150=6.66milliHertz or .00666 Hz which is a very low frequency. Duty Cycle: DC=PW/P=25/150=16.6% Your example uses seconds. it is more common to see examples in microseconds or less. The math is the same.


Describe how to calculate each of wavelength speed and frequency if you know the other two factors What is the wavelength of a 25 hertz wave traveling at 35 cms?

1). Frequency = (speed) / (wavelength)2). Wavelength = (speed) / (frequency)3). Speed = (frequency) x (wavelength)Use #3:Wavelength = (35 cm/s) / (25 Hz) = 1.4 cm
