A 2.00 m long string has a mass of (A + 1.50) g. A (B + 25.0) g mass is attached to the string and hung over a pulley (see illustration from one of the team problems). The end of the string is then vibrated at a frequency of (125 + C) Hz. Find the wavelength for the wave generated. Give your answer in centimeters (cm) and with 3 significant figures.
A = 13 B = 427 C = 7
Given that:
Mass of string, M = 13 + 1.50 g = 14.50 g = 0.01450 kg
Length of the string, L = 2 m
Linear mass density of string is given by:
Tension on the string, T = mg = (427 + 25) x 10-3 kg x 9.8 m/s2 = 4.4296 N
Therefore, Speed of wave is given by:
Frequency of wave, f = 125 + 7 Hz = 132 Hz
Therefore, Wavelength of the wave is given by:
