Question

The notes produced by a tuba range in frequency from approximately 45 Hz to 375 Hz. Find the possible range of wavelengths in air produced by the instrument when the speed of sound in air is 343 m/s. smallest wave

Answer 1

Answer:

The possible range of wavelengths in air produced by the instrument is 7.62 m to 0.914 m.

Explanation:

Given that,

The notes produced by a tuba range in frequency from approximately 45 Hz to 375 Hz.

We need to find the possible range of wavelengths in air produced by the instrument when the speed of sound in air is 343 m/s.

The speed of a wave is given by :

$v=f\lambda$

$\lambda=\dfrac{v}{f}$

$\lambda_1=\dfrac{343}{45}=7.62\ m$

$\lambda_2=\dfrac{343}{375}=0.914\ m$

So, the possible range of wavelengths in air produced by the instrument is 7.62 m to 0.914 m. Hence, this is the required solution.
