Period is 1/440s = 0.00227 to 3 significant figures.
440 Hz = 440 s^(-1) = 2.272... x 10^(-3) s Hence in one minute . 2.272... x 10^)-3) x 60 = 0.13536346.... min
The period of an 8000 Hz sine wave is 0.125 milliseconds. (1/8000)
Frequency = reciprocal of period = 1/P = 1/0.008 = 125 Hz.
Period = 1 / frequency = 0.001 second.
0.02
The period is the reciprocal of frequency, so for a frequency of 440 Hz, the period would be 1/440 seconds, which is approximately 0.00227 seconds.
The fundamental frequency of a violin string is 440 Hz, so its second harmonic would be twice that frequency, which is 880 Hz.
You want to tune a guitar's 'A' string to 440 hz.
The second harmonic of a frequency of 440 Hz is 880 Hz. It is exactly twice the frequency of the original sound wave.
The first harmonic of 220 Hz is 220 Hz, the second harmonic is 440 Hz, and the third harmonic is 660 Hz. These harmonics are multiples of the fundamental frequency (220 Hz) that create different pitches when combined.
The wavelength of the tuning note A440 can be found using the formula: wavelength = speed of sound / frequency. The period can be calculated using the formula: period = 1 / frequency. For A440 (440 Hz), frequency is 440 Hz, speed of sound is approximately 343 m/s, so the wavelength is around 0.779 meters and the period is approximately 0.00227 seconds.
The wavelength of a 440 Hz wave in air can be calculated using the formula: wavelength = speed of sound in air / frequency. The speed of sound in air at room temperature is approximately 343 m/s. Therefore, the wavelength of a 440 Hz wave in air is approximately 0.780 meters.
The frequencies of violin strings are typically G (196 Hz), D (293.7 Hz), A (440 Hz), and E (659.3 Hz).
440 everyones tuners are too

The frequency of a 440 Hz note in music is the pitch commonly used as the reference point for tuning instruments. It is known as the standard tuning pitch, meaning that most instruments are tuned so that the A above middle C corresponds to a frequency of 440 Hz.
Higher notes have higher frequencies. A typical tuning fork vibrates at 440 Hertz. That's the tone of the A above middle-C on a piano. The A one octave higher is 880 Hz (2 x 440 Hz). The A one octave above that is 1760 Hz (2 x 880 Hz). The A below middle-C is 220 Hz (440 Hz ÷ 2), the next lower A is 110 Hz, and so on. The lowest note on a piano is 27½ Hz, and the highest is 4186 Hz.
