To apply Problem-Solving Strategy 12.1 Standing waves and normal modes. A cellist tunes the C string of her instrument to a fundamental frequency of 65.4 Hz H z . The vibrating portion of the string is 0.600 m m long and has a mass of 14.4 g g . With what tension must she stretch that portion of the string? What percentage increase in tension is needed to increase the frequency from 65.4 Hz H z to 73.4 Hz H z , corresponding to a rise in pitch from C to D? What is U, the mass per unit length of the string? To determine the wave speed from purely kinematic quantities, you need to know the wavelength of the wave. What is the wavelength λ λ of the fundamental mode in the C string of the cello?.

Standing waves on a 1.5-meter long string that is fixed at both ends are seen at successive (that is, modes m and m + 1) frequencies of 38 Hz and 42 Hz respectively. The tension in the string is 720 N. What is the fundamental frequency of the standing wave? Hint: recall that every harmonic frequency of a standing wave is a multiple of the fundamental frequency. What is the speed of the wave in the string? What is the...

a. A guitar string is vibrating with a wave having a wavelength of 1.6 m. This string has a linear mass density of 20 g/m. If the tension holding the string is 7500 N, what is the frequency pitch of the sound produced? Answer in 2 decimal places, and units assumed in Hz. b. Echolocation is a technique used by some animals such as bats, whales and dolphins to assess their surroundings without using vision. A whale gets too far...
