Question

Middle C also known as "do" on the fixed do-solfege scale, is a note used when playing or singing music. The frequency of middle C is 261.63 HZ, and the wavelength is 131.87 cm. What is the speed of sound for middle c ?

Answer 1

Answer:

198.2m/s

Explanation:

Speed of a wave(v) is the product of the frequency of the wave (f) and its wavelength(¶).

Mathematically, v = f/¶

Given frequency of the middle C = 261.63Hz

Wavelength = 131.87cm

Converting this to meters we have;

131.87/100 = 1.32m

Speed of the sound = 261.63/1.32

Speed of the sound = 198.20m/s

Therefore the speed of sound for middle C is 198.2m/s
