A string is tied at both ends. When tuning forks of various frequencies are struck near the string, it is found that only the 10 Hz and 20 Hz tuning forks cause the string to vibrate. Someone tells you that the 20 Hz mode is 2 modes higher than the 10 Hz mode. What is the LNRF (lowest natural resonant frequency) of the string?
