Question

a tuning fork is of frequency 516 Hz and produces wave 65cm in length in air . the speed of sound in air is

Answer 1

f = frequency = 516 Hz.
λ = wave length = 65 cm = 0.65 m

speed of sound wave = v = f × λ 
v = 516 * 0.65 = 335.40 m/sec

Answer 2

Hey there,

velocity=frequency*wavelength

v=fλ

v=516*0.65

Therefore velocity=335.4 m/s
