The speed of a wave in a certain medium is 960 ~m / s . If 900 waves pass over a certain point of the medium in half a minute, the wavelength of the wave is

Options

  1. A16 ~m
  2. B32 ~m
  3. C9 ~m
  4. D18 ~m

Correct answer

B. 32 ~m

Step-by-step solution

v=960 ~m / s =? 900 waves passes in 30 sec . 30 waves passes in 1 sec v=30 = v v = 960 30 =32 ~m
