Unformatted text preview: 5 Hz. The intensity I = 1 2 p 2 c . p = 5 103 Pa and = 1 . 29 kg/m 3 , so I = 2 . 9 108 w/m 2 . Intensity level= 10 log I I = 44 . 7 db . 4. The velocity c = q T/ . The wave length can be 2 L/n , where n = 1 , 2 , 3 ... . The frequency f = c/ = n 2 L q T . 5. I = 1 2 p 2 c . The ratio R = I 1 I 2 = p 2 01 p 2 02 . From p = Pkz and k = 2 / = 2 f/c , we calculate R = k 2 1 z 2 01 k 2 2 z 2 02 = ( f 1 z 01 ) 2 ( f 2 z 02 ) 2 = 4 9 1...
