The string of a piano that produces a middle c note vibrates with a frequency of 2.64x10(2) Hz.?

whats the speed of sound in air, if the sound waves produced by this string have a wavelength in air of 1.30m?

The string of a piano that produces a middle c note vibrates with a frequency of 2.64x10(2) Hz.?
Clue: what are the units of the Speed of sound? Meters/sec?





multiply the wavelentgh (m) by the frequency (sec^-1)





so 264 sec^-1 x 1.3 m = 343 m/s (1125 fps)

Reply:beats the hell out of me. Ive been playing for 40 years. ( i have a failight and a babay grand a vox and a triton) been with bands for 25 years. Ive been considered a great touch and i can tune both the piano and figure out whats wrong electronically with my equipmetn. but i cant figure out why anyone would wantt o know this. except to waste his or her time. lol. seroiusly . just how much do you think the ear can hear? you remind me of the tone deaf singing. it just is chaotic and wrong. but if you make a better keyboard than whats out there. im all for it. ill play that too .though i cant imagine anyone noticing the difference. good luck!
