Question: Three successive resonance frequencies for a certain string are 75, 125, and 175 Hz. (a) Find the ratios of each pair of successive resonance frequencies.

Three successive resonance frequencies for a certain string are 75, 125, and 175 Hz.

(a) Find the ratios of each pair of successive resonance frequencies.

(b) How can you tell that these frequencies are for a string fixed at one end only rather than for a string fixed at both ends?

(c) What is the fundamental frequency?

(d) Which harmonics are these resonance frequencies?

(e) If the speed of transverse waves on this string is 400 m/s, find the length of the string.
