Answer:
The speed of the sound wave is 350 m[tex]s^{-1}[/tex]
Explanation:
Given
Frequency of sound wave = 1000Hz = 1000[tex]s^{-1}[/tex] (since 1 [tex]s^{-1}[/tex] = 1 Hertz (Hz))
Wavelength of sound wave = 35 cm
Speed of sound wave = ?
All waves have same the relation among frequency, sound and speed which is given by
v=fλ , where
v is the speed
f is frequency
λ is wavelength
Therefore, the speed of sound wave = 1000[tex]s^{-1}[/tex] x 35 cm
= 35000 cm[tex]s^{-1}[/tex]
= 350 m[tex]s^{-1}[/tex]
Hence the speed of the sound wave is 350 m[tex]s^{-1}[/tex]
