[SOLVED] Assignment Question Help! - Tuning Fork/ frequency I've talked to numerous people who can not figure out this question, so if anyone has any ideas on how to do this question please help me! A tuning fork is struck and held next to a vibrating guitar string, and beats of frequency 3 Hz are heard. The guitar string is tightened slightly, and the beat frequency decreases to 2 Hz. What is the new frequency of the guitar string? Explain your reasoning.
