In the “Resonance” lab, you used a “piano” to generate a frequency of 261.63 Hz to explore the different resonance lengths. With it you found the first resonance close to 33 cm. Where would you expect to find the next resonance?

A.66cm

B. 99 cm

C. 49.5 cm

D. 132 cm

please show work

in the “Resonance” lab, you used a “piano” to generate a frequency of 261.63 Hz to explore the different resonance lengths. With it you found the first resonance close to 33 cm. This resonance was found in an atmosphere of air. What would happen if you replaced the air with helium? Note that the speed of sound in helium is 972 m/s. The speed of sound in air is 343 m/s.

A. The first resonance would be found at a length shorter than 33 cm because the wavelength decreases.

B.The first resonance would be found at a length larger than 33 cm because the wavelength decreases.

C.The first resonance would be found at a length shorter than 33 cm because the wavelength increases.

D.The first resonance would be found at a length larger than 33 cm because the wavelength increases.

Musical notes have names (A,B,C, etc). The lowest A on a piano is called A0. If you go up an octave, the next A would be called A1. An octave higher, A2. The A near the middle of the keyboard is A4 (also called "concert A"). A similar pattern is true for all the notes. In a certain set of organ pipes, the speaking length (that's an effective physical length) for the pipe that makes the note E5 (f=660 Hz)...
