Two violinists, one directly behind the other, play for a listener directly in front of them. Both violinists sound concert A (440 Hz).
What is the smallest separation between the violinists that will produce destructive interference for the listener? Assume that the speed of sound is 343 m/s.

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.

Sorry i don’t know what to do

What does the start look like
