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...

Identical cellos are being tested. One is producing a fundamental frequency of 128.9 Hz on a string that is 1.40 m long and has a mass of 109 g. On the second cello an identical string is fingered to reduce the length that can vibrate. If the beat frequency produced by these two strings is 3.25 Hz , what is the vibrating length of the second string?

Two piano strings have the same length (0.7 cm) and mass density
(16 grams/meter), but the tension of one string is 6% greater than
the first. If beats with a frequency of 5 Hz are observed when the
third (n=3) harmonics of each string are excited simultaneously,
what is the tension of the string with the lower pitch (frequency)?
Answer in newtons to the nearest newton.

Identical cellos are being tested. One is producing a fundamental frequency of 248 Hz on a string that is 1.06 m long and has a mass of 100.0 g. On the second cello the same string is fingered to reduce the length that can vibrate. If the beat frequency produced by these two strings is 4.0 Hz, what is the vibrating length of the second string? (Express your answer to the nearest hundredth of a meter.) _____m I got 1.13m,...

6. Two identical speakers are emitting sound of the same frequency. Speaker 1, located 5 m away, has a sound level of 76 dB. Speaker 2, located 10 m from you, has a sound level of 73 dB. Assuming spherically radiating sound waves, which of the two speakers is producing the sound at higher power? 7a. Express the fundamental frequency of a piano wire fixed at both ends in terms of its tension FT, length L, radius r, and the...

The G string on a violin has a fundamental frequency of 196 Hz. It is 31.0 cm long and has a mass of 0.500 g. While this string is sounding, a nearby violinist effectively shortens the G string on her identical violin (by sliding her finger down the sting) until a beat frequency of 4.00 Hz is heard between the two strings. When that occurs, what is the effective length of her string? ___cm (please write solution legibly)
