5. A tuning fork is struck and placed over a cup of 1Neuter. Describe the standing wave that is ereeted. Both are nodes The tuning fork is en entinede and the 1Neuter is an sntinede The tuning fork is an antinede and the 1mater is a node Both are entinedes 9. A string of length 1.23 m vibrates in such a way that a standing wave with wavelength 0.820 m forms. What harmonic is the string vibrating at? first harmonic third harmonic second harmonic fourth harmonic10. A wave travels down a string with a velocity of 512 m/s. If the string has a length of 6.84 meters, what is the second harmonic frequency of this string? 3500 Hz 37.1 Hz 165 Hz 74.9 HZ
