(II) An unfingered guitar string is 0.68 m long and is tuned to play E above middle C (330 Hz).
(b) What is the wavelength on the string of this 440-Hz wave?

(II) A meteorite traveling 9400 m/s strikes the ocean. Determine the shock wave angle it produces

(b) in the water just after entering. Assume T = 20 °C.

(II) A tight guitar string has a frequency of 540 Hz as its third harmonic. What will be its fundamental frequency if it is fingered at a length of only 70% of its original length?

(II) A pipe in air at 21.5°C is to be designed to produce two successive harmonics at 308 Hz and 352 Hz. How long must the pipe be, and is it open or closed?

(II) A uniform narrow tube 1.50 m long is open at both ends. It resonates at two successive harmonics of frequencies 275 Hz and 330 Hz. What is

(a) the fundamental frequency, and
