Problem #5 Consider a string that is tensioned between two xed ends. The speed of any trans- verse waves on the string is 384 m/s. You know that two successive (their orders differ by 1) standing wave modes have frequencies 525 HZ and 630 HZ. You know that on the string you can create also standing waves for some frequencies lower than 525 Hz and for some frequencies higher than 630 Hz. Find the length of the string
