A `75 cm` string fixed at both ends produces resonant frequencies `384 Hz and 288 Hz` without there being any other resonant frequency between these two . Wave speed for the string is

A string is stretched betweeb fixed points separated by 75.0 cm . It observed to have resonant frequencies of 420 Hz and 315 Hz . There are no other resonant frequencies between these two. The lowest resonant frequency for this strings is
