A shower stall measures 94.0 cm 94.0 cm 230 cm. If you were singing in the shower, which frequencies will sound the richest (because of resonance). Assume that the stall acts as a pipe closed at both ends, with nodes at opposite sides, and that the voices of various singers range from 130 Hz to 2000 Hz. Let the speed of sound in the hot shower stall be 355 m/s.
