1/40 = 0.025 Hertz
It seems you are talking about radio waves. The wavelength (40 m) multiplied by the frequency (7 million / second) must equal the speed of light (300 million meters/second). It seems that in this example numbers, either the wavelength or the frequency, or both, are not expressed with a great accuracy. For example, if 40 meters is exact, the frequency would be close to 7.5 MHz.
t = 0.025 s Then f = 1/t f = 1/0.025s f = 40^(-s) or 40 Hz.

The frequency of the wave can be found using the formula: frequency = wave speed / wavelength. Given that the wave speed is 40 cm/s and the wavelength is 8 cm, the frequency would be 40 cm/s / 8 cm = 5 Hz.
1/40 = 0.025 Hertz
To find the frequency of the wave, you can use the formula: frequency = speed / wavelength. Given the speed is 40 cm/s and the wavelength is 8 cm, you can calculate the frequency as 40 cm/s / 8 cm = 5 Hz.
The frequency of the wave can be calculated using the formula: frequency = speed / wavelength. Plugging in the values, the frequency would be 40 m/s / 4 m = 10 Hz.
The frequency of a wave is the reciprocal of the period. In this case, the frequency would be 1 divided by 25 milliseconds, which equals 40 Hertz (Hz).
The wave speed can be calculated using the formula: speed = frequency x wavelength. Given the frequency of 10 Hz and a wavelength of 4 meters between crests, the speed of the wave would be 40 m/s.
The wavelength of a 40 Hz wave can be calculated using the formula: wavelength = speed of sound / frequency. For example, for sound traveling at 343 m/s (speed of sound in air at room temperature) a 40 Hz wave would have a wavelength of approximately 8.6 meters.
A sound wave with a frequency of 125 Hz has a wavelength of 40 meters (speed = frequency x wavelength). At a speed of 5000 m/s, this sound wave would have a period of 0.08 seconds (period = 1 / frequency).
First of all there is no definition of retangular wave. Maybe your retangular is my square wave. and the answer is inconclusive unless you specify the 40% level.

wavelength=velocity/frequency (v/f). wavelength=(3x10/4x10)=30/40=.75 meters
To find the wavelength, first calculate the frequency of the wave using the oscillator's vibrations per second (40 vibrations in 30s). The frequency is 40/30 = 1.33 Hz. Next, calculate the speed of the wave using the distance traveled in 10s (425cm in 10s = 42.5 cm/s). Finally, use the formula: wavelength = speed / frequency to find the wavelength: 42.5 cm/s / 1.33 Hz ≈ 31.95 cm.
