A B The Table Below Shows The Frequencies In Hz For The First Five Harmonics Of A Few Different Strings Copy The Tab 1 (60.11 KiB) Viewed 30 times
a-b) The table below shows the frequencies (in Hz) for the first five harmonics of a few different strings. Copy the table on paper and fill in the blanks (alternatively you can use Excel/Sheets or similar to produce and fill the table and export as pdf for submission online). H1 H2 H3 H4 H5 8 # 48 7.5 32000 211 c) A colleague of yours measures a higher harmonic for the first string (row one in the table above). She finds a frequency of 27 Hz. Assuming that you expand the table above with more columns to the right in which column will this frequency belong? Explain your answer.
You observed a fundamental standing wave of 85 Hz (n=1) on a string that is fixed at both ends. What is the 4th harmonic frequency?
You heard a 4th harmonic wave of 68 Hz not knowing anything else in a GSCI 121 standing wave lab. Find its 2nd harmonic wave frequency. Submit Answer Tries 0/10
a-c) Draw the standing wave patterns for the first four harmonics on the string shown below. For each case complete the equation showing the relationship between the wavelength A and the length of the string L. If the length of the string is 1.3 m and the frequency of the first harmonic is 10 Hz, calculate the wavelength and the period for each harmonic. NOTE: Reproduce the table below on paper, draw and fill in the information required, then scan as pdf and submit. Harmonic # Standing Wave Pattern A as a function of Length [m] 1 L = 2 3 4 L L L
