Blog Post 7: Laser Simulation

We used the 4 different quadrants on the top of the slide.  Brad and I labeled them 1 through 4 in this order.

Slide 1

Slide 2

Slide 3

Slide 4

For slides 1 and 3 the pattern on the quadrant is horizontal lines.  Slide 1 the lines are thinner and more frequent, and on slide 3 the lines are thicker and less frequent.

For slides 2 and 4 the pattern on the quadrant is vertical lines. Slide 2 the lines are thinner and more frequent, and on slide 4 the lines are thicker and less frequent.

On slides 1 and 2 we calculated the space between the lines to be 80 nm, and each line is 60 nm thick.
For slides 3 and 4 we calculated the space between the lines to be 120 nm, and each line is 60 nm thick.

Blog Post 5: Wave Interference Simulation Activities

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

1) wavelength = 5.24 cm: low frequency, high amplitude

2) wavelength = 5.27 cm: low frequency, low amplitude

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

1) 5.02 cm: low frequency, mid amplitude

2) .95 cm: high frequency, mid amplitude

3. Explain your results for Question 1 and 2.

amplitude has no effect on the wavelength, it is the frequency that can dramatically change the wavelength.

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

- measure the wavelength of the two drips, in cm

#1 wavelength = 2.91 cm

#2 wavelength = 2.91 cm

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

Drip 1 distance to:

A: 3.72 cm

B: 4.45 cm

C: 4.43 cm

D: 8.06 cm

E: 7.66 cm

F: 7.76 cm

Drip 2 distance to:

A: 4.12 cm

B: 4.69 cm

C: 7.99 cm

D: 4.56 cm

E: 7.89 cm

F: 11.12 cm

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


the points become more frequent when the two different wavelengths start to interfere with each other, and because of that the wavelengths become seemingly shorter.
