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".
A wave with a period of 2.5 seconds per cycle is a wave with one cycle per 2.5 seconds, or 1/2.5 cycles per second. That's 0.4 cycles per second or 0.4 Hertz.
It turns out that the frequency and the period of a wave are reciprocals. One over the frequency equals the period, and one over the period is the frequency.
Of course the expression needed to have a relation between frequency, wavelength needs the speed of sound waves. That changes with the temperature. In this case temperature is not mentioned. Any how let us assume the temperature to be 0 deg C, then the speed of sound in air can be taken to be 330 m/s.
The mathematical relation is lambda = speed / frequency
Hence lambda (wavelength) = 330/250 =1.32 m
The speed of sound through a medium depends on that medium's bulk (elastic) modulus and density, not the wave's frequency and wavelength.
A hertz (Hz) is a single cycle per second. The period indicates how long each wave lasts.
Therefore, a wave with a frequency of 250 hertz has a period of 1/250th of a second.
Wave speed is simply frequency multiplied by wavelength.
1.2m * 250Hz = 300m/s
The sound wave travels 1.2 m in 1/250 second or 1.2*250 m/s = 300 m/s. Note that period = 1/frequency.
if the period is 0.25 seconds, then the frequency is 4Hz.

The speed of the sound wave is 325m/s.
1/4 or .25 F hope this helps
It means the the wave has a speed of 25 vibrations per second
1). Frequency = (speed) / (wavelength)2). Wavelength = (speed) / (frequency)3). Speed = (frequency) x (wavelength)Use #3:Wavelength = (35 cm/s) / (25 Hz) = 1.4 cm
Reciprocal of frequency gives the period SO T = 1/ n Or T = 1/40000 = 25 microsecond
The "pitch" of the sound is determined by its frequency.(It would be much more elegant to call that a "characteristic"or a "property" of the sound, not a "part" of it.)
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
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
