A string 2.0 m long and fixed at both ends is vibrating in its fourth harmonic in a room at 20C.The wavelength of the sound it produces is 1.0 m.

Question

Quizplus · Accepted Answer

The wavelength of a sound wave is given by the formula λ = 2L/n, where L is the length of the string, n is the harmonic number, and λ is the wavelength. Substituting L = 2.0 m and n = 4, we get λ = 0.5 m, which is different from the given wavelength of 1.0 m. Therefore, the statement is false.
