In eq. (10.1) in the lab manual, the constant rhoυ is 41.1 gm-cm−2sec−1 in air. a piece of paper has a mass per unit area of approximately 7x10−3gm/cm2. if the frequency is 4.1 khz, what does theory predict for the ratio of the transmitted amplitude to the incident amplitude of the sound wave? (a sound wave is a pressure wave.)
