Good evening good evening

Today we started off quite quickly. We worked on a pink sheet called Chart for Evaluating the Models of Light where we would prove or disprove different theories.

We read many topics in our booklet as well including:

4.2 Early Attempts to Produce and Interference Pattern in Light
4.3 Young's Experiment
4.4 Young's Experiment: Interference at Three Angles
4.5 Young's Experiment and Deriving a Useful Equation

Once our reading was completed we continued to do an experiment. We took a ring stand with a clamp and clamped a meter stick right in the middle. Below the meter stick we placed a lamp, and we covered it with different colored films, then we took 2 slides that had a little slit that you could look through. We distanced ourselves 2 meters away from the meter stick and looked through the slit, and we found out how many nodal lines there were in 10 centimeters

And that's about it!
The next scribe shall be: Dana!
