Vertical and horizontal barriers would make the patterns we saw. they way that i look at it if you end up with a vertical line then the barriers need to be horizontal to make that happen and vice versa.

Blog Post 5: Wave interference Sims

1. Measure the wavelength of two drops of different amplitude, leave frequency constant. Drop 1 is 1.73cm and Drop 2 is 1.67cm

2. Measure the wavelength of two drops with different frequency, leave amplitude constant. Drop 1 is 4.45cm and Drop 2 is 1.07 cm

When you change the amplitude of a wave you do not change the energy therefore your wavelength should be exactly the same. any differences are due to human error in the measuring process.

When you change the frequency of a wave you are changing its wavelength because frequency and wavelength are directly related.

4. Introduce a second faucet for the next set of questions.

- measure the wavelength of the two drips, in cm

- then measure distances from each drip(red dots) to the 6 constructive interference points (yellow dots) and report these values, cm

the wavelength of the drops of water were both 1.2 cm.

distance from faucet one then two respectivly 

A=3.08 cm,4.54 cm

B=3.06 cm, 2.99 cm

C=4.57 cm, 2.97cm

D=4.62 cm, 6.32 cm

E=4.7 cm, 4.47cm

F=6.18 cm, 4.41 cm
