On beating an object sound is produced. the sound waves so produced is longitudinal or transverse.?

Question

I just had this question in my mind. So i think i require a precise answer with perfect explanations

Answer 1

Precise and perfect? Let's not get too demanding!
All sound transmitted through air is a longitudinal wave. So that's half the answer. But you also produced a sound wave in the structure of what you were beating upon. These waves could be transverse or longitudinal. It depends on the "mode shape" of the vibration and the direction of travel, if any, of the wave in the structure. Most structures "ring" at one or more frequencies. This ringing is due to "standing" waves, which have their maximum and minimum displacements in the same locations; the wave does not travel in the structure. In this case the definition of longitudinal and transverse gets imprecise, since those terms normally describe vibration direction with respect to travel direction. But in many cases, like a vibrating string or membrane, we say it's a transverse wave because the vibration direction is perpendicular to the major dimensions of the string or membrane. And it's longitudinal if it's along a major dimension as in the example above of an end-whacked stick.

Answer 2

It depends where you hit the object. Take for example the familiar "crack" sound when a wooden bat comes in contact with a baseball. That's the transverse wave, which is more like plucking a guitar string. Take the same bat and hit it on the end with a hammer(similar to hammering a spike into a wooden plank). You get a very high pitched sound. That's the longitudinal wave.

Answer 3

A- Sound waves: Because of pulses given to the surrounding air. and-B- heat waves: Dynamic Energy is being transferred to Heat Energy. and D-Electrical energy, if the movement is within magnetic field. and finally, if the electric energy from D is is suitably transformed and trnsferred through a circuit to a bulb, Light will come from.

Answer 4

sound waves are longitudinal waves... being the rarefaction and compaction of airwaves.
