It takes a 200-g mass to create 3 segments of a transverse wave pattern using a string of length 30.0 [cm] and density 0.0112[g/cm3 ]. What is the frequency (in [Hz]) at which the string is vibrating?

Answer #1

If the string is vibrating in the three segments, then the relation between length of the spring and the wavelength of wave is,

The velocity of the wave inside stretched string is given as,

here, T = Mg= 0.200*9.8 = 1.96 Newton

m = 0.0112gm/cm3 = 11.2 kg/m3

Hence the frequency will be,

A standing wave pattern is created on a string with mass density μ = 3 × 10-4 kg/m. A wave generator with frequency f = 63 Hz is attached to one end of the string and the other end goes over a pulley and is connected to a mass (ignore the weight of the string between the pulley and mass). The distance between the generator and pulley is L = 0.68 m. Initially the 3rd harmonic wave pattern is formed....

10. [1pt] Consider a transverse harmonic wave travelling along a string. Enter true (T) or false (F) for the following statements. For example, if the first statement is true and the rest false, enter TFF. You have 4 tries. Increasing the amplitude of the wave increases its frequency. If a wave with a frequency of 10 Hz travels along a string with a mass per unit length of 40 g/m stretched to a tension of 100 N, its wavelength is...

A = 18, B = 693, C = 3. The speed of a wave in a string is given by v = sqrt(FT/μ), where FT is the tension in the string and μ = mass/length of the string. 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...
