Question

solve it for brainlist..​

Answer 1

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 :-

• $\huge\green\star$ $\bf\pink{\lambda\:=\:\dfrac{c}{\nu}\:}$

Where,

$\bf\red{\lambda}$ = Wavelength

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

$\bf\red{\nu}$ = Frequency

☯︎ According to the question,

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

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

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

$\bf\blue{:\implies\:\lambda\:=\:1.289\:m\:\approx\:1.29\:m}\:$

$\huge\red\therefore$ The wavelength of sound is "1.29m" .
