A stretched string can oscillate in resonance at 1280. Hz and at 1536 Hz. There are no resonance frequencies between the frequencies.

a. what is the fundamental resonance frequency of the string?

b. what is the length of an organ pipe, open at both ends, that has the same fundamental frequency as the string? (Assume that the velocity of the sound in air is 343.0 m/s)

c. Would the organ pipe of part (b) also be capable of resonance at 1536 Hz.

d. What is the length of an organ pipe, open at one end and closed at the other that has the same fundamental frequency as the string? (Assume that the speed of sound in air is 343 m/s)

e. would the organ pipe of part (d) also be capable of resonance at 1536 Hz.
