Two identical guitar strings are prepared such that they have the same length (0.64 m) and are under the same amount of tension. The first string is plucked at one location, primarily exciting the third harmonic. The other string is plucked in a different location, primarily exciting the fifth harmonic. The resulting sounds give rise to a beat frequency of 369 Hz. What is the wave propagation speed on the guitar strings?

A 38.0-Hz sound wave is barely audible at a sound intensity level of 60.0 dB. The density of air at 20.0°C is 1.20 kg/m3. Speed of sound in air at 20.0°C is 343 m/s. What is the displacement amplitude of a 38.0-Hz sound wave? What is the ratio of the displacement amplitude to the average distance between molecules in air at room temperature, about 3.00 nm?

A block of mass 2.5 kg sits on a frictionless 30° incline and is attached with a string to a wall so it does not slide down. The string has a linear density of 1.3 g/m. What is the speed of a wave traveling in the string?

A wave travels along a steel string with a speed of 22 m/s. At some point along the string, its diameter doubles. What is the speed of the wave in this thicker part?

The power versus time for a point on a string (μ = 0.05 kg/m) in which a sinusoidal traveling wave is induced is shown in the preceding figure. The wave is modeled with the wave equation y(x, t) = A sin(20.93 m−1 x − ωt). What is the frequency and amplitude of the wave?

A transverse wave is traveling on a string. The displacement y of a particle from its equilibrium position is given by y = (0.021 m) sin (25t - 2.0x). Note that the phase angle 25t - 2.0x is in radians, t is in seconds, and x is in meters. The linear density of the string is 1.9 × 10-2 kg/m. What is the tension in the string? F= MO

A string consists of two parts attached at x=0. The right part of the string has mass per unit length 12.8 g/m and the left part has mass per unit length 3.2g/m. The string tension is T. If a wave of amplitude 3.5cm travels along the left part of the string, what is the amplitude of the wave that is transmitted to the right part of the string?

These two waves travel along the same string: Y₁ = (3.61 mm) sin(2.03πx - 380лt) Y2 = (5.73 mm) sin(2.03лx - 380πt +0.818лrad). What are (a) the amplitude and (b) the phase angle (relative to wave 1) of the resultant wave? (c) If a third wave of amplitude 5.32 mm is also to be sent along the string in the same direction as the first two waves, what should be its phase angle in order to maximize the amplitude of the new resultant wave? (a) Number i (b) Number (c) Number Units Units Units

A string experiences several harmonic frequencies. Two successive frequencies are 325Hz and 390Hz. a) What is the fundamental frequency? b) What is the next harmonic higher than 195Hz? c) Which harmonic is this?
