Question

A string, stretched tight, is observed to vibrate with a fundamental frequency of 50 Hz. We then vibrate the string at the frequencies shown below. Which frequency would NOT produce a standing wave on the string? Not enough information to determine 200 150 100 25

Answer 1

Fundamental frequency is the lowest frequency for which a standing wave pattern can be set up in the string.So below the fundamental frequency a standing wave pattern can not produce on the string.Here fundamental frequency is 50 Hz.Since 25 Hz is below the fundamental frequency ,so it can not produce standing wave pattern.

Ans: option(E) 25 Hz
