Acoustics and Sound Waves: Principles, Calculations, and Applications1. Standing waves have regions of minimum amplitude callednodesand regions ofmaximum amplitudecalledantinodes.-----------------------------------------------------------------------------------------------------------------------------2. Thedecibelscale is a logarithmic scale used for comparing sound levels.-----------------------------------------------------------------------------------------------------------------------------3. An open organ pipe (both ends open), 16 feet long, is operating in air at 20Β°C. Thefundamentalfrequency f1 = __________ Hz and the second harmonic frequencyf2 = __________ Hz (1 ft = 0.3048m).in a pipe open at both ends, the natural frequencies of oscillation form a harmonicseries that includesall integral multiples of the fundamental frequency:𝑓𝑛=𝑛𝑣𝐿𝑛=1,2,3,…Therefore:𝑓1=𝑣𝐿=343(16βˆ—0.3948)=πŸ“πŸ’.πŸ‘π‘―π’›π‘“2=2×𝑣𝐿=2Γ—343(16βˆ—0.3948)=πŸπŸŽπŸ—π‘―π’›-----------------------------------------------------------------------------------------------------------------------------4. Suppose the air is replaced by helium at 20Β°C (v= 1005 m/s). For an open pipe (both endsopen), 16-ftin length, the new fundamental frequencyf1 = __________ Hz.𝑓1=𝑣𝐿=1005(16βˆ—0.3948)=πŸπŸ“πŸ—π‘―π’›-----------------------------------------------------------------------------------------------------------------------------5. In order to produce a fundamental frequency of 10 Hz in a stopped organ pipe (one end closed),therequired lengthL= __________ m.𝑓1=𝑣𝐿==>𝐿=𝑣𝑓1=34310=πŸ‘πŸ’.πŸ‘π’Ž
