Sound's frequency stays the same across mediums. To find it's frequency, we can use v = λ f inputting knowns:
330 m s = 5.5 m f Solve for f:
f=60Hz
Knowing this, we can find the wavelength λ in the other medium:
v = λ f Inputting knowns:
1324 m s = λ 60 H z Solve for λ :
λ = 22   2 3 m or λ = 22.67 m in decimal form.
