Lab report

Design an experiment:

Go to the (https://phet.colorado.edu/sims/html/wave-interference/latest/wave-interference_en.html) to do the experiment choose Slits.

For two slits, use the equation 

????????????????(????)=????????

to predict to where on the screen the maxima will appear. Use the tape measure to verify your predictions.

10 steps to design an experiment and conduct it:

1. The purpose of the lab (can be finding more than one thing, for example wavelength of the source, the position of the 1st bright band,  the intensity of the central bright band or something else. It has to be something that you can calculate theoretically, or you know the actual value, so you can compare your experimental results with. May be you can start with the theory)

2. It is useful to identify what quantities can be changed, what quantities can be measured. 

3. in your experiment you need to do several trial for measurements for accuracy.

4. When conducting the experiment, you can only change one quantity at a time.

5. make a table to help yourself to collect data and collect dat

6. Present data (tables or graphs)

7. Analyze the data  (includes calculations of experimental values and theoretical values, error calculations)

8. Discuss your analysis, your data and your errors

9. Make a Conclusion

10.  Report everything in a formal lab report format

Write a 5 pages lab report and please  

strictly follow the example format and 10 steps to design an experiment.
