Question

A loudspeaker produces sound waves that change in wavelength from 1.0m to 1.5m. If the wave speed is constant, how did the vibration of the loudspeaker change?

Answer 1

Answer:

I am not sure but the reason can be the change in medium . As it is known that sound travels faster through denser compounds . The reason for this is that since the particles are closer in dense compounds than rare compounds , the vibration occurs faster .

One of the scenario could be that there was a large bowl or any other container of water kept in front of the loudspeaker . When the waves reched the water , the vibration took less time to transfer from particle to particle .
