You create a sinusoidal wave on a stretched spring by holding the end of the spring and moving your hand back in form in simple harmonic motion. What would happen to the wavelength and speed of the wave if you increased the oscillation frequency of your hand?

1. nothing
2. both wavelength and speed would increase
3. both wavelength and speed would decrease
4. wavelength would increase; speed would stay the same
5. wavelength would decrease; speed would stay the same
6. wavelength would increase; speed would decrease
7. wavelength would decrease; speed would increase
8. wavelength would stay the same; speed would increase
9. wavelength would stay the same; speed would decrease
