Example 18.7 The Mistuned Piano Strings Two identical piano strings of length 0.775 m are each tuned exactly to 400 Hz. The tension in one of the strings is then increased by 1.0%. If they are now struck, what is the beat frequency between the fundamentals of the two strings? SOLVE IT Conceptualize As the tension in one of the strings is changed, its fundamental frequency changes. Therefore, when both strings are played, they will have different frequencies and beats...
