1. Speed of Sound
In this virtual investigation you will find the speed of sound in solids, liquids, and gases. You will fill a tube with a chosen material and send sound from a tuning fork through the tube. A detector will pick up the sound at the other end of the tube and show you the speed of sound in that material. You will record the data for all the materials. From your data you will draw conclusions about sound and states of matter. Will the speed of sound be different in a solid, liquid, or gas?In this virtual investigation you will find the speed of sound in air at different temperatures. You will fill the tube with air at a chosen temperature and send a sound from a tuning fork through the tube. The detector will show you the speed of sound at the chosen temperature. You will record data for all the given temperatures. From your data you will draw conclusions about sound and temperature. Will the speed of sound be different for the different temperatures of gas?
