Explanation / Answer

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.
