Well a Hz is a unit of frequency. It's define as the amount of time it takes pattern to oscillate in one full cycle.
so 12 Hz is the oscillation of a cycles 12 times per seconds.
A billion.
12^2 + 12 = 144 + 12 = 156 or, 12^2 + 12 = 12(12 + 1) = (12)(13) = 156
12
12 x 12 x 12 x 12 x 12 = 125 = 248,832
The Answer Is 12 12 x 12 x 12 = 1728 12 x 12 = 144 144 x 12 = 1728
3 cycles / 12 seconds = 0.25 cycles / second, or 0.25 Hz.3 cycles / 12 seconds = 0.25 cycles / second, or 0.25 Hz.3 cycles / 12 seconds = 0.25 cycles / second, or 0.25 Hz.3 cycles / 12 seconds = 0.25 cycles / second, or 0.25 Hz.
Brain waves can be measured in units of frequency, typically in Hertz (Hz). The main types of brain waves are delta waves (0.5-4 Hz), theta waves (4-8 Hz), alpha waves (8-12 Hz), beta waves (12-30 Hz), and gamma waves (>30 Hz). These frequencies correspond to different states of consciousness and mental activity.
This is straight from Wikipedia Delta up to 4 Hz Theta 4 - 7 Hz Alpha 8 - 12 Hz Beta 12 - 30 Hz Gamma 30 - 100 + Hz {| ! ! ! ! ! ! | |}
Difference is in their frequency, audible sound waves is between 12 Hz and 20,000 Hz, Ultrasound waves is any sound that has a frequency beyond the 20,000 Hz limit
The speed of a wave is calculated by multiplying the wavelength by the frequency. In this case, the speed of the wave would be 12 m/s (2m * 6 Hz = 12 m/s).
c = λ × f λ in meter f = 1/T Hz = 1/s Therefore, C= 2 (m) X 6 (Hz)= 12 m/s
The hearing frequency range for sheep is estimated to be 100 to 30,000 Hz. Sheep have a lifespan of 10 to 12 years.

Frequency of femal adult is 165 hz to 255 hz.
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.
mega = 1,000,000 1MHz = 1,000,000 Hz.
The energy of a photon is given by the equation E = hf, where h is Planck's constant (6.626 x 10^-34 J s). Substituting the frequency f = 6 x 10^12 Hz into the equation gives E = (6.626 x 10^-34 J s) x (6 x 10^12 Hz) = 3.98 x 10^-21 J.
