why when the window is open in a car the wind comes in so sporadically when driving
In: 32
It’s like blowing across the top of a bottle to make the whistling sound. A car with one open window is the exact same thing – a volume of air with wind blowing across a single opening. And you’re inside the “bottle”.
The bigger the air cavity, the lower the frequency of the resonating air. That’s why bigger bottles whistle a lower note. The car is like a really big bottle, so the frequency is so low it just sounds like thumping.
