Ripple While You Work
Purpose: To observe wave phenomena in ripple tank (applet)
Directions:
Go to http://www.falstad.com/mathphysics.html
Click on ripple tank applet
STEP ONE: Change the drop down window from 1 src, 1 frq to No sources
Click the mouse at random in the window. You can increase the brightness if this helps.
1. Describe the shape of the pulse. Does the speed of the pulse seem to be the same in all directions?
It is square ripples centered around the mouse and then they turn to circles. The ripples are even all the way around.
STEP TWO: Change the drop down window from No sources to 1 plane src, 1 freq. You can change the simulation speed and source frequency if you want.
2. What is the shape of the pulse? How is …show more content…
STEP FIVE: PLAY AROUND but try to answer these questions.
5. What happens to waves when they encounter obstacles of different shapes? Why do you think that happens? Well, there is more ripple interference and the shape remains circles but not perfect circle ripples all around. This happens because they are reflected off of different shaped objects and not just flat objects sending the ripples in multiple directions.
6. How does the wave pattern for a single slit vs. a double slit compare? Why do you think that …show more content…
This is happening because when there is only one slit it just being displaced right in the middle and basically keeps one main ripple afterwards. When there is two, there is more displacement and the ripples become more spread out.
7. How does a plane source vs. plane source interact with an obstacle of different shapes? Why do you think that happens?
8. Examine a moving source. Describe the wave patterns behind the source. What happens when you change the frequency? The speed? When a source is moving it reminds me of a boat moving through water, the ripple behind it starts out small and then continues to grow. When the frequency is increased it just creates more waves and same goes for when its decreased, less waves. Although when the source speed is changed the waves act different. When it is extremely slow the waves are created all around the source and not just behind it, but when it is fast that’s when the waves are just created behind the source.
9. Generate some wave (either plane or single source). What happens when you click on the wave pond? Why do you think that happens? It generates alittle displacement and creates the square shaped ripples but then the ripples continue on and go back to even ripples of
