Question

ip two violinists, one directly behind the other, play for a listener directly in front of them. both violinists sound concert a (440 hz).

part a

part b

part c
repeat part a for violinists who produce sounds of 540 hz.
(d = )

Explanation:

Calculate the wavelength of the sound wave

$$ \lambda = \frac{v}{f} = \frac{343\text{ m/s}}{540\text{ Hz}} \approx 0.63519\text{ m} $$

Determine the minimum distance for destructive interference

$$ d = \frac{\lambda}{2} = \frac{0.63519\text{ m}}{2} \approx 0.31759\text{ m} \approx 0.32\text{ m} $$

Answer:

Repeat part A for violinists who produce sounds of 540 Hz.

\(d =\) <blank>\(0.32\text{ m}\)</blank>
