Frequency f = 500 Hz
speed of sound v = 343 m/s
wavlength = d
v = fd
343 = 500 x d
d = 0.686m
wavenumber = 1/wavelength = 1/d = 1/0.686 = 1.46
period = T = 1/f = 1/500 = 0.002 s
cyclical frequency = 2 pi f = 2 x 3.14 x 500 = 3140
only 1 st question is to be answered as per the posting rules.
Still thesecond one is very similar to the solution i have provided and can be worked out.Please do not post multiple questions together.
