Question

im confused on all of this...

Lab-Assignment 23 Resonance 7/30/20 Resonance is the dramatic amplification of vibrational amplitude due to a force vibrating an object at its characteristic frequency Resonance for an open organ pipe occurs when there is an antinode at both ends of the pipe. All harmonic frequencies are integer multiples of the smallest frequency to match this boundary condition. The smallest frequency consists of half of a cycle. Resonance for a closed organ pipe occurs when there is an antinode at the open end of the pipe and a node at the closed end. All harmonic frequencies are odd integer multiples of the smallest frequency to match this boundary condition. The smallest frequency consists of a quarter of a cycle. 5) For the fifth harmonic frequency of a closed organ pipe, there are Discussion Questions Circle the correct answer. [1] For the third harmonic frequency of a closed organ pipe, three halves / five halves / three fourths/five fourths of a cycle is present in the pipe. 12] For the second harmonic frequency of an open organ pipe, one two three / four cycles are present in the pipe. 13] If a closed organ pipe and an open organ pipe both have the same fundamental frequency, then the open organ pipe is longer shorter same in length. 1 For the third harmonic frequency of an open organ pipe, there are nodes in the interior of the pipe. nodes in the interior of the pipe. Fill in the blanks with a number.

Answer 1

a closed thrice fewer they five fourths 2 2 of the cycle So, Second harmonic CS Caen Scanner then for organ pipe, first harmonic = 1/4th of a cycle so, Third harmonics, 2 the of acycle pogan as for the third harmonics frequency of a closed pipe, three halves/ five hatres, of a cycle. is present in the pipe. 2. for open organ pipe, first harmonic 1 of the cycle pipe, za for second harmonic frequency of an open sogan oney two / three / four cycles 3. for oposed pipe, for open pipe, 210 Now, same no, ale 4. are present in the pipe. ho AL V no 21 for or, 210 = 416 or lo =2le both of For the third harmonic there are three 17 If a closed organ pipe and an open organ pipe have the same fendamental foequency, then the open organ pipe is longes Y shorter / same in length. frequency of an open organ pipe nodes in the interior of the pipe. horr ma nice feequency of organ pipe, nodes in the interior of the pipe ham mavée frequency 6. For closed organ pipe, the is the next bight néghest resonant focquerey 5. For the fifth harmonice, "frequency of a closed three there are third frequency above the trop
