Unformatted text preview: What will be the lowest frequency sound wave that will produce a standing wave in an aluminum bar that is 0.2 m long? ( Assume that standing waves will still occur when the length is an integer multiple of l /2 and that the termini will be pressure minima, though there will be no phase reversal at the free ends). f = 12.8 kHz NB: These answers are irrespective of significant figures....
