Utilizing the difrfaction slides and laser pointers address the following questions.

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.

Top Left-Fine Vertical Dotted Line
Top Right-Fine Horizontal Dotted Line
Bottom Left-Rough Vertical Dotted Line
Bottom Right-Rough Horizontal Dotted Line

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


The distance is approximately estimated at 150nm for the rough horizontal and vertical lines and about 80nm for the fine horizontal and vertical lines

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.

4. Green Light is able to measure smaller things much better than red light due the the lower wavelengths.
