If the wavelength of a sound source is reduced by a factor of 2, what happens to the waves frequency?
What happens to its speed?

Here is an example that shows that the frequency can double and the speed can stay the same.
Example 1: the sound is traveling in one direction and reflects from a train moving toward you so fast that the returning energy has half the wavelength of the original sound.
The sound is traveling in the same medium (say, air), so the speed of sound is the same.
Other examples that involve changes in speed but not frequency have to do with sound energy going from air into, for example, water. In this case, the frequency stays the same, but the wavelength changes and so does the sound speed.

What is the relationship between frequency and wavelength? Does the speed of sound depend on the frequency or the wavelength?

wavelength = velocity/frequency
if the wave length reduces by 2, then the frequency goes up by 2

The shorter the wavelength, the faster the frequency is...And the longer the wavelength, the slower the frequency is...

You've given insufficient information to answer this completely and correctly. Are you dividing the frequency by 2 or are you reducing the output level by 2 or ½?
The speed is unchanged; it still travels at the speed of sound.
Hope this helps, somewhat ;-)

Doubles. If wavelength is the time between peaks then when you cut that in half you should get 2x more waves in the same amount of time.

Sebastian=HUNK Cade sounds attractive too Jackson is likewise a recognition that i detect appealing Royce & Jace= homosexual sounding (no offense to every physique with that call!) that is something regarding the "ce" sound on the top of those 2. all the others are purely primary/in between for me. yet this is purely my opinion lol
