An organ pipe that is opened at both ends and is near a heating pipe such that the temperature is 35.00 C. The fundamental frequency is 5000 Hz. A) How long should the pipe be ?B) What is the frequency of the next harmonic ? C) If there is asecond organ wit the same pipe in a normal room at 20.00C. What is the 'beat' frequency between the two fundamentalfrequencies ?
