Please solve 9
Dear student,
(a) Figure i shows principal note
(b) figure iii is fourth harmonic so its frequency is four times that of i.
(c) the wavelength in i is equal to the length of the string, so its wavelength is longest.
(d) figure ii is 2nd harmonics, so its wavelength is half of i. so their frequency will be in the ratio 1:2
Regards
