1. Measure the wavelength of two drops of different amplitude, leave frequency constant.
A) The first wavelength I measured was 1.89cm. This was at low amplitude, while keeping frequency constant.
B) The second wavelength I measured was again 1.89cm. This was at high amplitude, while keeping frequency constant.
2. Measure the wavelength of two drops with different frequency, leave amplitude constant.
A) The first wavelength I measured was 4.60cm. This was at a low frequency, while keeping amplitude constant.
B) The second wavelength I measured was 1.26cm. This was at high frequency, and again keeping amplitude constant.
3. Explain your results.
The results in question 1 and two conclude one thing; wavelength is dependent on frequency and independent of amplitude.
4. Introduce a second faucet for the next set of questions.
-measure the wavelength of the two drips in cm
The wavelength of the two drips is 2.81cm.
- then measure distances from each drip to the 6 constructive interference points and report these values, cm
Using the picture below, I measured distances from points X and Y, to the six points of my choice, where there is constructive interference. The results are as follows:

- explain the observation you have on the distance comparisons to the constructive interference points to the wavelength of the water wave. I observed the distance to the middle point between both drips (point C) is roughly equal. Points E and F are furthest away from origin X, and are the longest distances. These two distances match up and are almost identical to the two furthest points from origin Y, which are points D and F. Also point B from origin X is the same distance as point A from origin Y. The greater the distance between the wavelengths the more destructive the interference, and the shorter the distance between the wavelengths the more constructive the interference, generating a higher frequency. | |||||||||||||||||||||||||||||||
