Problem

An open pipe of length

0.50\,\text{m}

produces its fundamental note at

20^{\circ}\text{C}

with frequency

343\,\text{Hz}

. Assuming the speed of sound in air varies as the square root of the absolute temperature, determine the fundamental frequency of the pipe at

40^{\circ}\text{C}

. (Take temperature in kelvin.) a)

366\,\text{Hz}

355\,\text{Hz}

332\,\text{Hz}
