Velocity of Sound in Air What is a longitudinal wave Is the wave that has the same direction of vibration as its direction of travel, which means that the movement of the medium is in the same direction as or the opposite direction to the motion of the wave. Mechanical longitudinal wave has been also referred to compression wave . In a longitudinal wave the particle displacement is parallel to the direction of wave propagation What is a transverse wave ? Is a moving wave that consists of oscillations occurring perpendicular (or right angled) to the direction of energy transfer. If a transverse wave is moving in the positive x-direction, its oscillations are in up and down directions that lie in the y–z plane . In a transverse wave the particle displacement is perpendicular to the direction of wave propagation

Unformatted text preview: How does sound travel in air ? Sound is the transfer of energy in the form of waves. The waves travel by bumping air molecules together. The air molecules move back and forth, but the wave of energy moves outwards. The speed with which the waves travel through air depend solely on temperature . What are the natural frequencies of oscillation formed in a pipe that is open at both ends and a pipe open at one end and closed at the other ? f= v/2L where v is the speed of longitudinal wave in the rod . The longest wavelengths possible are : a) 2 L b) 4 L You find the frequency from the ratio . frequency = speed of sound/wavelength Added : L is the length of the pipe ....

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
