Question

$\huge\red{\boxed{\blue{\mathcal{\overbrace{\underbrace{\fcolorbox{blue}{aqua}{\underline{\red{QUESTION}}}}}}}}}$
Calculate wavelength of sound wave whose frequency is 220 Hz and speed is 440 m/s.

Answer 1

Formula -

⇒ Velocity = Wavelength × Frequency    

⇒ Using the above mentioned formula

⇒ v = λ × n  

⇒ where λ denotes Wavelength and n denotes frequency

Given,

v = 440 m/sec

n = 220 Hz  

λ = ???    

v = λ × n    

440 = λ × 220  

=> λ = 440 / 220  

=> λ = 2

WAVELENGTH (λ) = 2 m  

ANSWER = 2 m
