A wave travels at 114 m/s and has a wavelength of 2.8 m. Calculate the wave frequency (in Hertz). Calculate the wavelength (in m) of a 396 Hz sound in air at room temperature and pressure where the velocity of sound is 344 m/s. If the tension (i.e., force) on a string increases 13 times but the density of the string remains constant, the new speed of waves on the string will be how many times greater than the original speed? A 35 Hz wave has a wavelength of 0.4 m. Calculate the speed of the wave (in m/s) A wave is sent back and forth along a rope 4 m long with a mass of 0.9 kg by exerting a force of 30 N. Calculate the linear mass density of the rope (in kg/m). Calculate the air temperature (in degrees Kelvin) if the speed of sound is 353.7 m/s (at standard air pressure). Calculate the speed of sound in a string that has a tension of 454 N and a linear mass density of 0.0001 kg/m. What is the wavelength (in m) of a 12 KHZ sound wave in a material where the speed of sound is 1540 m/s? Calculate the speed of a wave (in m/s) in a material if the frequency is 677 Hz and the wavelength is 0.5 m. If the length of a string increases 9 times but the mass of the string remains constant, the new density of the string will equal the original density multiplied by what number?
