Question
This lab uses the Waves Interference simulation from PhET Interactive:
Develop your understanding: Open the Interference screen, then explore to make water waves with varying patterns.
-Use the Water Level tool to understand what is happening in the water tank:
a. Measure the dark and light areas of waves made with only one faucet. Insert a screen image to help explain your answer.
b. Make waves using both faucets and measure the dark, light and fuzzy spots. Insert a screen image to help explain your answer.
c. What do you think constructive and destructive interference means based on your measurements?
d. Verify your understanding using your text or online references. (cite references)
Develop your understanding: Open the Slits screen, then explore to make water waves with varying patterns.
Explain your understanding:
7. How do waves made by a dripping faucet compare to the waves seen passing through slits? You may want to have both Interference and Slits open (or open the full simulation Waves Interference), so that you can easily compare the waves and their patterns.
8. Do the same concepts apply when you compare the sound and light waves in Interference and Slits screens?
9. Summarize your understanding of waves as they pass through slits. Make sure you demonstrate meeting learning goal C "Put up a barrier to see how the waves move through one or two slits. What sort of pattern do the slits create? How can you change this pattern?"
