A student asked me a question on how to shows that refraction occurs in sound.
First of all, she has to understand the term 'refraction'. Obviously we know that refraction is the bending effect of a wave that travels from a medium to another medium of different density.
So in the case of sound wave, an experiment that can shows refraction does occurs in sound wave is shown above. As it travels from air into the balloon filled with carbon dioxide, due to differences in their density, the wave change direction. So microphone connected to the CRO is needed.
The question now is that how the display of waveform shown on the screen of CRO can be used to prove that refraction does occur?
Any improvement should be made here? Discuss with your friends and teacher about it.
Good luck...
