$\huge\mathbb{\blue{QUESTION -}}$

If the frequency of a sound wave is 990 Hz, calculate its wavelength. (Assume the air temperature is 0°C.) = ________ m

$\huge\mathbb{\blue{SOLUTION-}}$

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

• Frequency (f) = 990 Hz
• Velocity of sound at 0°C is = 331.2m/s

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

• Wavelength ${\sf \lambda}$

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

$\large{\boxed{\bf \pink{\lambda = \dfrac{v}{f}}}}$

$\implies{\sf \lambda= \dfrac{33.1}{990} }$

$\implies{\bf \red{\lambda =0.368\:Hz} }$

$\huge\mathbb{\blue{ANSWER-}}$

Wavelength will be ${\bf \red{\lambda = 0.368\:Hz}}$
