When two waves of same frequency travel in a medium simultaneously in the same direction, then due to their superposition, the resultant intensity at any point of the medium is different from the sum intensities of the two waves. (ii) Pitch or Frequency Pitch of sound directly depends on frequency. In physics, a wave is a disturbance that transfers energy through matter or space, with little or no associated mass transport. I had worked really hard for searching the best stuff for my project and I hope you'll find this helpful. [The difference of frequencies should not be more than 10.
