The wavelength increased the slower the finger was dipped in.
When you move your finger to the right, the wavelength decreases, causing a higher frequency. This means that it has more energy than the water behind your finger.
Conclusion: 1. The wave lengths are smaller in front of the finger.
2. The wave lengths are larger behind the finger.
3. The waves behave this way because the light source is moving away from the object,
therefore creating more distance between the two.
4. When an object moves towards you it would produce blue light, because the waves
are more frequent.
