In this experiment, sound waves are created with the use of speaker connected to a function generator. The function generator sends an oscillating current signal to the speaker which causes the speaker's diaphragm to vibrate.he material properties of the medium determine the speed with which the sound wave travels through that medium. For example, the speed of sound in water is approximately 1500m/s and through a diamond the speed can reach 12,000m/s!
Miyazaki's film was financed by executive producer Yasuyoshi Tokuma, and both My Neighbor Totoro and Grave of the Fireflies were released on the same bill in 1988. The dual billing was considered one of the most moving and remarkable double bills ever offered to a cinema audience.
