3 Oscillations & Waves

Speed of Sound

To determine the speed of sound waves in air using the resonating air columns.

Standing Waves

To investigate standing waves in stretched nylon strings set up by mechanical driver; to measure the distance between two nodes for 6 wavelengths; to plot the wavelength vs square root of tension in the string , where T = mg and m is a mass suspended over the pulley; to determine the frequency of vibrator from the slope.
