Blog Post 7: Diffraction Experiment with Simulation

1. What is the 4 patterns printed on the slides? Somehow draw and post this pattern on your blog, and explain how you arrived at this pattern.

Our Distance from the light source (laser) to the wall is 1m

The first two squares showed dots in a horizontal pattern

The first one has a diffraction grating similar to this

Green dots are 1cm apart

Red dots are 1cm apart

While the second is similar to this
each green dot being 1.25cm apart
each red dot is 1.5cm

The third and fourth squares showed dots in a horizontal line

The first one the green dots were 1 cm apart
the red dots are 1cm apart

the square has a grated pattern like this

The second grated square showed green dots 1.25cm apart
and red dots 1.5cm apart

With a grated pattern like this

2. Determine the distance between the line patterns, and how think the lines may be.

160nm and thickness of the lines is 60nm (roughly)

3. Setup the light wave simulator to simulate the patterns on the 35 mm slides. Grab a picture of these simulations and post them for each of your patterns.
