2) Graph the following data on standard Cartesian graph paper:
(0.3, -1) (1.7, -1) (3, 2) (4, 0) (5.7, -1) (7, 2) (9, -2) (10, 0) (11.7, 1) (13, -2) (14, 0) (15, 2) (15.7, 1) (18, 0) (19, 2) (20, 0)
3) The horizontal axis is given in cm and the vertical axis is in mm. What is the amplitude of this wave? What is the wavelength of this wave? Can this single wave display interference?
4) Now consider another wave that has the same amplitude and the same wavelength. Is it possible to set up these two waves so that there is constructive interference? If so, how?
5) Now, is it possible to set up these same two waves so that there is destructive interference? If so, tell how and also tell how much shift total there must be between the constructive interference in the previous question and the destructive interference here.
6) Study the following link: https://plus.maths.org/content/physics-minute-double-slit-experiment-0 On the following page, write at least two full paragraphs about wave-particle duality. Include what we see with photons and what we see with electrons. Do you find this surprising? Can you suggest why we see this with electrons but would not see it with, for example, baseballs?
7) What is the difference between energy and intensity as far as light waves are concerned? How would you change the energy? How would you change the intensity? Are these changes independent of one another? Why or why not?
8) Discuss what changes you might expect to see if the energy of the light wave was changed for the double slit experiment. Why?
9) Discuss what changes you might expect to see if the intensity of the light wave was changed for the double slit experiment. Why?
10) Write at least two full paragraphs to summarize what you did in this lab. Be sure to include anything you learned, had clarified, or still don’t understand.
