Question
A sound wave has a frequency of
440 Hz and is traveling at
343 m/s through air. Your classmate claims the wavelength is
1.5 × 105 m. In 1-2 sentences, assess whether this claim is true and explain why or why not. If it is not true, give the correct wavelength.
Can you give me the correct answer please? Thank you

Your classmate's claim is false. The wavelength (λ) can be calculated using the formula \( \lambda = \frac{v}{f} \), where \( v \) is the speed of sound (343 m/s) and \( f \) is the frequency (440 Hz). Therefore, the correct wavelength is \( \lambda = \frac{343 \, \text{m/s}}{440 \, \text{Hz}} \approx 0.780 \, \text{m} \).
