Question

a traveling force frequency 170hz produced sound wave of wave length 2meter calculate speed of sound​

Answer 1

Explanation:

given that

frequency =170hz

wavelength = 2m

velocity = frequency × wavelength

v=170×2

v=340m/s

Answer 2

$\Large\underline{\underline{\sf Given:}}$

• Frequency of travelling force (f) = 170Hz

• Wavelength $\sf{\lambda}$=2m

$\Large\underline{\underline{\sf To\:Find:}}$

• Speed of sound (v) = ?

$\Large\underline{\underline{\sf Formula\:Used:}}$

$\large{\boxed{\boxed{\sf \pink{v=f \lambda}}}}$

$\Large\underline{\underline{\sf Solution:}}$

$\implies{\sf v=f \lambda }$

$\implies{\sf v=170×2 }$

$\implies{\sf v=340\:m/s}$

$\Large\underline{\underline{\sf Answer:}}$

⛬ Speed of sound is 340 m/s
