d) A stretched string of mass 20 g vibrates with a frequency of 30 Hz in its fundamental mode and the supports are 40 cm apart. The amplitude of vibrations at the antinode is 4 cm. Calculate the velocity of propagation of the wave in the string as well as the tension in it.
Introduction This question involves calculating the wave velocity and tension in a stretched string vibrating in its fundamental mode. We are given frequency, length, and mass of the string, and are asked to calculate the wave speed and tension. Given Mass (m) = 20 g = 0.020 kg Length (L) = 40 cm = 0.40 […]
