ok first you find the wavelength λ which is 2x the distance between 2 antinodes X and Y. sohttp://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Physics (9702)/9702_s12_qp_12.pdf
Ok so I'm done with every single thing except this question which is literally haunting me :'( plzzz plzzzz plzzzz if some1 knows it answers it pleaseeeeee it's Q:30
λ= 2x 33cm = 66cm = 0.66m
and then v=f λ so f= v/ λ=330/0.66=500
we know that period (T) = 1/f = 1/500 = 0.2ms for 1 oscillation
so answer is B
