How does increasing the tension of a string affect various properties?

[GalacticSnipes]

This isn't really a homework question, just a question i got wrong on test and want to understand:
If the tension of a string increases how would the following be affected (Increase, decrease, stay the same, not enough info)?
1. The fundamental frequency of vibrations on a string?
2. The wavelength of the standing wave on a string?
3. The wavelength of the sound waves produced by the string?
4. The frequency of the sound waves produced by the string?
5. The speed of the standing waves on a string?
6. The speed of the sound waves produced by the string?
If someone could "enlighten" me that would be much appreciated, and please tell me why the answers to these questions are what they are. :)
