Question

how to find wavelength of sound. Pls tell with a sum

Answer 1

hope it help you.......

Answer 2

Count the number of waves passing each second (= frequency), and multiply by the length of each (= wavelength) to find the speed. speed = distance/time = l/T= l / (1/f) = f λ. Work through three examples: A simple example, perhaps for sound in air, with values in Hz and m.
