This is EXACTLY the kind of recipe I had been searching for! Super easy, lots of greens, and great taste! Seriously, I used almost a 2 whole cups of spinach in mine and with the banana and milk it doesnât taste bad at all. Thanks for this recipe, it gives me no excuses not to get my greens in:) Reply.
The laws of sound physics (acoustics) or How does it work? The human ear can generally hear sounds with frequencies between 20 Hz and 20 kHz (the so called âaudio rangeâ). 20 Hz is a very low frequency while 20 kHz is a very high frequency. Examples of low frequencies in our surroundings are the bass in music or the low humming that a fan generates. Examples of high frequencies are the treble in music or the high notes of a small child.
Fundamental and Harmonics. The lowest resonant frequency of a vibrating object is called its fundamental frequency. Most vibrating objects have more than one resonant frequency and those used in musical instruments typically vibrate at harmonics of the fundamental.A harmonic is defined as an integer (whole number) multiple of the fundamental frequency.Vibrating strings, open cylindrical air columns, and conical air columns will vibrate at all harmonics of the fundamental. Cylinders with one end closed will vibrate with only odd harmonics of the fundamental.undamental and Harmonics.
