1/25 Hz
frequecy and period have an indirect relationship F=1/4s =.25 Hertz
Simply using the relation wavelength = velocity / frequency So required wavelength = 25/5 = 5 m
Freq = Speed/Wavelength = 37.5/25 Hz = 1.5 Hz
25 years = 788,923,149 seconds.
600 seconds would be 10 minutes, then add the other 25 seconds and... 625 seconds = 10 minutes and 25 seconds
frequecy and period have an indirect relationship F=1/4s =.25 Hertz
1/4 or .25 F hope this helps
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".

It means the the wave has a speed of 25 vibrations per second
Simply using the relation wavelength = velocity / frequency So required wavelength = 25/5 = 5 m
25 waves are produced in 20 seconds , so 25 ÷ 20 = 1.25 waves in 1 second ... so the Frequency is 1.25 Hz
5 metres per second. V (velocity) = Distance/Time = 25/5 = 5
Freq = Speed/Wavelength = 37.5/25 Hz = 1.5 Hz
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
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.
1). Frequency = (speed) / (wavelength)2). Wavelength = (speed) / (frequency)3). Speed = (frequency) x (wavelength)Use #3:Wavelength = (35 cm/s) / (25 Hz) = 1.4 cm
