Please Help! If you send a sound wave of the same wavelength (λ = 2.00 m) through air, helium, and carbon dioxide, describe how the pitch of the sound will compare through each medium. Use calculations and your data to explain

Please Help!	If you send a sound wave of the same wavelength (λ = 2.00 m) through air, helium, and carbon dioxide, describe how the pitch of the sound will compare through each medium. Use calculations and your data to explain

@francesco.alemanno can you help?

I'm assuming you had some kind of data table that went with this... Pitch is determined by frequency, and frequency and density of the medium are inversely related.

anonymous · Answer

The density of air is about 1.29 kg/m^3, of helium .169 kg/m^3, and of carbon dioxide 1.98 kg/m^3. So the pitch would be highest for helium, in the middle for air, and lowest for CO2.
