Question

A turning fork makes 256 vibrations per second in air . when the speed of sound is 330m/s ,find the wavelength of the note emitted.

Answer 1

here wavelength => speed / frequency
=> wavelength => 330/256=> 1.2m

Answer 2

GIVEN :-

A tunning fork makes 256 vibrations per second in air .

The speed of sound is 330m/s .

TO FIND :-

The wavelength of sound .

SOLUTION :-

\$\bf\pink{\lambda\:=\:\dfrac{c}{\nu}$

Where,

$\bf\red{\lambda}λ$ = Wavelength

$\bf\red{c}c$ = Speed of sound

$\bf\red{\nu}ν$ = Frequency

According to the question,

$\bf\red{c}c$ = 330 m/s

$\bf\red{\nu}ν$ = 256 vibration per second

$\begin{gathered}\rm{:\implies\:\lambda\:=\:\dfrac{330}{256}\:}\:\\\end{gathered}$

:⟹λ=1.289m≈1.29m

[tex]\huge\red\therefore[\tex]The wavelength of sound is "1.29m" .
