• # question_answer Sound travels with a speed of about$330\text{ }m\text{ }{{s}^{-1}}$. What is the wavelength of sound whose frequency is 660 Hz? A) 5 m                             B) 50 m   C)        0.5 m  D)        500 m

Speed of sound, ${{v}_{s}}=330m{{s}^{-1}}$ Frequency of sound, $v=660Hz$ $\therefore$ Wavelength of sound,             $\lambda =\frac{{{v}_{s}}}{v}=\frac{330}{660}=\frac{1}{2}=0.5m$
