Question 1 Not yet answered Points out of LOCI '{2 Flag question If you have standing waves in air, in an openopen tube of length L, then the formula for nding the wavelength of the different harmonics I1 is A = O a. = 4L with 11: 1,3,5... odd numbers 0 b. = 4L with n =1,2,3,4,5, ....... O c. = 2L with n: 1,2,3,4, ...... 0 d. = 2L with n: 1,3,5,7,9, ...... Question 2 Not yet answered Points out of 1.00 13' Flag question 100k at the standing wave here is this in a tube with open ends, closed end, or open- closed ends? 0 a. closed ends 0 b. open ends 0 0. open- closed ends Question 3 Not yet answered Points out of 1.00 P Flag question Which harmonic is this standing wave? (first recognize if it is in open-open, open-closed or closed-closed tube) O a. first O b. fourth O c. second O d. thirdQuestion 5 Not yet answered Points out of 1.00 P Flag question Look at the standing wave here - it is the harmonic. ( first recognize if it is in open-open, open-closed or closed-closed tube) XXX O a. 3rd O b. and O c. 1st O d. 4thQuestion 6 Not yet answered Points out of 1.00 {3 Flag question Look at the standing wave here The length of the tube is L = 2m. So the wavelength of the harmonic shown is meters. 0a. 1m 00. 6m 0:1. 2111 0e. 3111 Question 7 Not yet answered Points out of 2.00 P Flag question Here are the first and third harmonic in an open-closed tube. If the length of the tube is 3m then the wavelength of the first and third harmonic are _and O a. 12m and 6m O b. 6m and 2m O c. 12m and 4m O d. 6m and 3mQuestion 8 Not yet answered Points out of 2.00 P Flag question Here is an open-closed tube of L= 3m. Consider the standing wave shown. Recognize the harmonic and find wavelength so that you can calculate the frequency of this standing wave knowing the speed of sound is v= 340m/s. freq = A. 85 B. 4080 C.28.3 D. 340 E. 1360
