Count its' complete 360 degree cycles. (That will take skill and maybe some electronics.) From a given point back to that point again. Divide that into time. Seconds for Hertz. Minutes for RPM.
An octave is a factor of 2 in the frequency. So, just divide 1200 Hz. by 2, then divide the result by 2 again.
The other note's frequency would be either 365 Hz or 375 Hz. Since the beat frequency is the difference in frequencies between the two notes, you can either subtract or add the beat frequency to the known frequency to determine the other note's frequency.
The second harmonic of a frequency of 440 Hz is 880 Hz. It is exactly twice the frequency of the original sound wave.
If the vibrating string has a natural frequency of 30 Hz, it will also be resonant at the odd harmonics of its natural frequency. Therefore, it will be resonant at 90 Hz, 150 Hz, 210 Hz, and so on, as these frequencies are multiples of the fundamental frequency (30 Hz).
The frequency would be 5 Hz, as hertz (Hz) is the unit used to measure frequency in waves per second.
If a bulb has 50 Hz frequency and it's supply is 60 Hz frequency, it will still glow, despite the allowance of 10 HZ frequency.
A 2,000 Hz signal has a wavelength of about 93.14 miles.
An octave is a factor of 2 in the frequency. So, just divide 1200 Hz. by 2, then divide the result by 2 again.
Frequency is measured by hertz, or Hz. 1 Hz is a frequency of one cycle per second, and as such a frequency of 60 flashes per second would yield 60 Hz.
The other note's frequency would be either 365 Hz or 375 Hz. Since the beat frequency is the difference in frequencies between the two notes, you can either subtract or add the beat frequency to the known frequency to determine the other note's frequency.
The second harmonic of a frequency of 440 Hz is 880 Hz. It is exactly twice the frequency of the original sound wave.

Of course. -- The frequency of my light bill is 1/month or 3.86 x 10-7 Hz. -- If I can rev my car up to 3,500 rpm, then it's cranking at a frequency of 50 Hz. -- Each of my dogs eats a bowlful at a frequency of 2.315 x 10-5 Hz, and I refill their water bowls at about 1.16 x 10-4 Hz. -- The frequency of Middle-C on my piano is about 240 Hz. (It hasn't been tuned in a while.) -- The frequency of horizontal motion of the spot on my TV screen is 15,750 Hz. I can't hear the TV picture but my dogs can. -- The frequency of the power supply that my computer and my lights run on ... the one that comes out of the wall socket ... is 60 Hz. -- The frequency of the US presidential election mechanism is 0.000000007922 Hz. -- The frequency of the Earth's axial rotation is 0.000011606 Hz. -- The frequency of my favorite falling-asleep radio station is 780 kHz, and of my favorite operating spot on ham radio is 3.735 mHz. -- The frequency of the signal that comes out of my little key-chain laser pointer is about 472,114 GHz.
If the vibrating string has a natural frequency of 30 Hz, it will also be resonant at the odd harmonics of its natural frequency. Therefore, it will be resonant at 90 Hz, 150 Hz, 210 Hz, and so on, as these frequencies are multiples of the fundamental frequency (30 Hz).
The frequency would be 5 Hz, as hertz (Hz) is the unit used to measure frequency in waves per second.
The fifth harmonic of a frequency is calculated by multiplying the frequency by the harmonic number. So, the fifth harmonic of 77 Hz would be 77 Hz x 5 = 385 Hz.
The frequency of a busy tone typically ranges from 480 Hz to 620 Hz.
