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.

Question

gebooors · Answer

Speed of sound is different in different gases.

Because speed = wavelength * frequency,  ( v = lambda * f)

Then f = v/ lambda.

If speed increases frequency increases. 
You have to find out speeds
 speed in air is 340 m/ s.
