In a standing wave,not necessarily at the fundamental frequency,on a string of length L,the distance between nodes is

D)L/4.
E)L/2.

Quizplus · Accepted Answer

The distance between nodes in a standing wave on a string of length L can be found using the formula d = λ/2, where d is the distance between nodes and λ is the wavelength of the wave. At any frequency other than the fundamental frequency, the wavelength will be shorter than the length of the string, so the distance between nodes will be less than L. Therefore, the only option that satisfies this condition is B, which gives d = λ/2.
