Question

a sound wave travel with a speed of 330 m/s what is the wave length of sound whose frequency is 550 hz

Answer 1

Answer:

Formula: Wavelength = Velocity of Light / Frequency

Given, Velocity of Light = 330 m/s and Frequency = 550 Hz

⇒ Wavelength = 330 m/s / 550 Hz

⇒ Wavelength = 0.6 m

Hence the wavelength of the sound wave is 0.6 m

Hope it helped !!

$\huge{\underline{\underline{\sf{\blue{SOLUTION:-}}}}}$

⠀

$\sf{\underline{\pink{Answer-}}}$

⠀

• The wavelength of sound waves is 0.6 metre.

⠀

$\sf{\underline{\pink{Given-}}}$

⠀

• A sound wave travel with a speed of 330 m/s.

⠀

• Frequency is 550 hertz.

⠀

$\sf{\underline{\pink{We\:Have\:To\:Find-}}}$

⠀

• We have to find the wavelength of sound.

⠀

$\sf{\underline{\pink{Explanation-}}}$

⠀

$\longrightarrow \: \sf\: Speed \: of \: the \: wave, \: v=330 \: m/s.$

⠀

$\longrightarrow \: \sf \: Frequency \: of \: waves, \: f= \: 550 \: hertz.$

⠀

$\longrightarrow \: \sf \: Wavelength, \: λ=? \sf \: (We \: have \: to \: calculate)$

⠀

$\sf{\underline\green{Formula\:Used\:Here-}}$

⠀

⠀$\bigstar\:\:\boxed{\sf{\red{v=f \times λ }}}$

⠀

$\sf{\underline{\pink{Putting\:the\:values:-}}}$

⠀

$\longrightarrow \: \sf \: 330 = 550\timesλ$

⠀

$\longrightarrow \: \sf \: λ= \dfrac{330}{550}$

⠀

$\longrightarrow \: \sfλ=0.6m$

⠀

• Thus, wavelength of sound waves is 0.6 metre.
