Study on the Characteristics of String Vibration |
| |
| Abstract: | According to the vibration mode and string length, the string line density can be measured when standing wave is formed in the metal string. At a given frequency, the wavelength under different tension is measured.The actual relationship is obtained between wavelength and tension by using the least square method. |

| Keywords: | string vibration standing wave linear density wavelength tension |
