Physics Daisy Khenchanthavong Period 5 5/12/12 Lab: audio frequency in Strings and Tubes I. access: The look sharp of big(a) is non constant, but varied. It varies with pressure, temperature, and where it is traveling finished. The vibrations of kinetic energy molecules stimulate the speed of live on, making the molecules adjacent and tightening their bonds. For example, audio frequency waves gutter go through solids much easier than moltens because, the molecules in solids argon close together and tightly bonded. Also, It is harder for sound to go through gases than liquid because the particles atomic number 18 much farther apart. Air is the lofty gas. The speed of sound through air at sea train is measured at 346m per second. String and wind factors are a great way to explain these procedures. String instruments bring out sounds by vibrating its lines, with low chuck outes from its long du ration or low tension, with gamy tipes from short length string or high tension. patch the wind instruments require almost the resembling but, use tubes kinda of strings. The wind instruments has a type of resonator, which a certain come up of air is set into vibrations of the instrumentalist blowing it, to help create sound. The length of the tube and manual modifications establishes the pitch of the sound by the players desire. In this lab, we leave behind determine the way a string and wind instruments make sound waves. II. Purpose: After this lab, you allow understand what factors, such as length, tension, and Thickness, affect sound in string and tube (wind) instruments. III. guessing: If the length of a string instrument is shorten, then the pitch depart become high because, of shorter wavelengths and higher tension in that string compared to the longer ones. If the can of a tube is unlikeable then the pitch will be lower because the wavelength will be b locked and the sound waves have to exit thro! ugh one hole. IV.
