7. Your goal is to determine the set of harmonic frequencies for the rope medium through which waves travel at 100 cm/s. Gradually increase the frequency until you find the frequency values that cause standing waves with 3, 4, 5, ... 10 nodes to form. Make sure the right end of the rope is a node before you record the frequency. Fill in the table on the next page. The last column is a calculated column; it asks for the frequency of the nth column divided by the frequency of the 1st column
