I will be working with Thomas Trostle and Steve O'Brien on the invention project.

Blog Post 7: Diffraction Experiment with Simulation

The numbers on this image correspond to the positions
Position 1 The distance between line patterns for green = 1 cm, red = 1.25 cm
Position 2 The distance between line patters for green = 1 cm, red = 1.25 cm
Position 3 The distance between line patters for green = 1.5 cm, red = 2 cm
Position 4 The distance between line patters for green = 1.5 cm, red = 2 cm

Position 1 and 2 are 80nm apart with a thickness of 60nm.
Position 3 and 4 are 120nm apart with a thickness of 60nm.

Blog Post 5: Wave Interference Simulation Activities

1. Measure the wavelength of two drops of different amplitude, leave frequency constant.
    low amplitude  : 4.34 cm
    high amplitude : 4.34 cm

2. Measure the wavelength of two drops with different frequency, leave amplitude constant.
    low frequency  : 6.52 cm
    high frequency : 0.98 cm

3. Explain your results for question 1 and 2.
    As you change the amplitude the wavelength does not change just the height of the wave, but when you change the frequency then the faster you have the frequency the smaller the wave length becomes.

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 to the 6 constructive interference points and report these values, cm

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

Wavelength of the two drips : 2.5 cm

X -> A ~ 3.47        Y -> A ~ 3.43
X -> B ~ 3.48        Y -> B ~ 6.11

X -> C ~ 6.10        Y -> C ~ 3.52

X -> D ~ 6.09        Y -> D ~ 8.59

X -> E ~ 6.03        Y -> E ~ 6.06

X -> F ~ 8.60        Y -> F ~ 6.08

The distance between the constructive interference points are about the same to a little bit bigger than the wavelength of the individual drip. 

Blog Post 3: Waves

Questions:
1. Fast up and down
2. High energy
3. 0.98 Hz
4. 3.7 Hz
5. 0.98 Hz
6. 58 cm
7. 16 cm
8. Energy is proportional to frequency because the higher the frequency the more energy is needed to make it.  If there is high energy then there is a lower wavelength but if there is low energy there is a higher wavelength.
