Blog Post 5: Wave Interference Simulation Activities

Blog Post 5

1. Measure the wavelength of two drops of different amplitude, leave frequency constant.
Amplitude = 1.34 cm Wavelength = 5.12 cm
Amplitude = .18 cm Wavelength = 5.12 cm

2. Measure the wavelength of two drops with different frequency, leave amplitude constant.

Frequency = 1.36cm apart Wavelength = 1.26 cm
Frequency = 1.98cm apart Wavelength = 1.98 cm

3. Explain your results for Question 1 and 2.

+/- Amplitude = same wavelength
+ Frequency = Shorter Wavelength / - Frequency = Longer Wavelength

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

- measure the wavelength of the two drips, in cm

x= 2.33cm

y= 2.33 cm

- then measure distances from each drip to the 6 constructive interference points and report these values, cm

x to 1= 2.96cm          y to 1= 2.96cm

x to 2= 2.96cm          y to 2 = 5.17cm

x to 3= 5.17cm          y to 3 = 2.96cm

x to 4= 7.28cm          y to 4 = 7.28cm

x to 5= 5.17cm          y to 5 = 5.17cm

x to 6= 7.28cm          y to 6 = 5.17cm

- explain the observation you have on the distance comparisons to the constructive interference points to the wavelength of the water wave.

Creates a PATTERN (of distance): 

 x/y to 1 & 5 = same distance  ,  x/y to 2 & 3 = same-opposite  ,    x/y to  4 & 6 = same-opposite
= Waves meet up at the same pattern.  Constructive (full waves) and Destructive (half waves) patterns. The dots meet at full wavelengths + their multiples.
