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 transverse wave has a frequency of ν = 74 Hz and a wavelength of λ = 11.5 m. The wave obtains a maximum displacement of ym = 2.5 m and propagates in the -x direction.  Given the form y(x,t) = A sin(B) for the displacement of the wave, input an expression for A. Using the same form y(x,t) input an expression for B. How fast is the wave traveling in m/s?

Two waves are traveling on the same string. The displacement of the first is given by y₁ = (0.200 m) sin [(400л s¯¹)t — (2л m¯¹)×] and of the second by y2 = (0.300 m) sin (400л s¯¹)t − (2ë m¯¹)x + x and y in meters and t in seconds. What is the phase constant of the resultant wave? i - rad wi , with

Two wave pulses A and B are moving in opposite directions, each with a speed v 5 2.00 cm/s. The amplitude of A is twice the amplitude of B. The pulses are as shown at t = 0. Sketch the resultant wave at t = 1.00 s, 1.50 s, 2.00 s, 2.50 s, and 3.00 s.

Your answer is partially correct. A transverse wave on a string has an amplitude of 0.188 m and a frequency of 215 Hz. Consider the particle of the string at x = 0 m. It begins with a displacement of y=0m when t = 0 s. How much time passes between the first two instants when this particle has a displacement of y = 0.0817 m? Number i -0.000332 Units S

A certain traveling wave on a string obeys the function: y1(x, t) = 0.5m cos((0.25π rad/m) x + (1.25π rad/s) t) What is the direction and speed of this wave? negative in the x direction and 5m/s 2b. A second wave is traveling on the same string in the opposite direction and is described by the function, y2(x,t) = 1.2m cos((5.75 rad/m) x - (2.50 rad/s)t). What is the direction and speed of this wave? positive in the x direction and 0.43m/s 2c. The two waves overlap at the point x = 0.47 m when t = 3.2 s, what is the amplitude of the string at this point and time? y1(x, t) = 0.5m cos((0.25π rad/m) (0.47) + (1.25π rad/s)(3.2))=? i get 0.47m is this correct? y2(x,t) = 1.2m cos((5.75 rad/m) (0.47) - (2.50 rad/s)(3.2))=? 0.66m is this correct? im looking for guidance on 2c   the one that has been answered on the site I don't understand how that answer was attained and need clarification
