Unformatted text preview: tuning fork. Record the length (L) of the wire to the bridge in meters. 9. Calculate the frequency of the string (f s ) using the formula f s =(1/[2L])[(TL)/M)]. 10. Repeat steps #19 using the lighter sonometer wire with a tuning fork of higher frequency if possible. Data Wire Vibrating String Lengt h (L) (meters) Load (kg) Calculated Tension (T) (N) Mass of Wir e (M) (kg) Frequency Calcul ated (f) (Hz) Frequency Measured (f) (Hz) Heavier Lighter Analysis The following points should be addressed in the analysis: How is a standing wave formed in a string? What is the nature of harmonics in a string? What factors could account for any variations between the calculated and actual values for the frequencies? What is the relationship between resonance and beat frequency? What factors influence the harmonics possible in the wire?...
