Hi guys, i'd really like to understand physics but for some reason I'm not coping. Not sure if it's the calculations or something. But I'm willing to learn, I'd appreciate some help with this problem:
A B string on a guitar with a length of 33cm is held fixed at both ends under tension. Once plucked, it ossicilates ata fundamental frequency of 264Hz.
i)What is the wavelength of the wave on the string?
ii) Sketch the pattern of displacement of the string.
iii) What is teh wavelength of the resulting sound in the air (assume the speed of sound in dry air at 0oC is 331m.s^-1)
------------
no equations were provided with the question.
-----------
my attempt:
i) c = f x lambda
lambda = c/f
lambda = 3 x 10^8/264
= 1136363.636
ii) not sure how to draw this... is there an online program so i can show my attempt?iii) lambda = 331/264
= 1.25
