Waves in a Ripple Tank: A Virtual Activity
Waves in a Ripple Tank: A Virtual Activity
Go to the site http://www.falstad.com/ripple/. A “Ripple Tank Applet” window will open that runs a simulation of waves generated in a ripple tank.
By “clicking on” any or all of the three task bars in the upper right hand corner of the applet window, you can change the type and number of wave sources. The third task bar allows you to use the mouse to edit the waves or walls (barriers). You can adjust the speed, resolution, frequency, brightness, and/or damping of the wave simulation to obtain a clearer representation of the wave phenomena. A complete and detailed set of directions for how to use this simulation is linked to the web page.
Your task is to use this web site to identify and investigate various wave properties and characteristics. You will hand in pictorial representations of…
Circular Wave
long wavelength
shorter wavelength
Plane Wave
long wavelength
shorter wavelength
Reflection
Plane Wave Off Angled Straight Barrier
Plane Wave Off Concave (Parabolic) Barrier
Circular Wave Off Straight Barrier
Diffraction
Plane Wave Around a Barrier
Plane Wave Through an Opening
Circular Wave Around a Barrier
Circular Wave Through an Opening
Refraction of a Plane Wave
Refraction due to Temperature Gradient (simulates sound wave over lake)
Interference
Two Circular Waves (wide spacing between sources)
Two Circular Waves (closer spacing between sources)
One Plane and One Circular Wave (this is a tricky one to simulate!)
Single Slit (plane wave)
Double Slit (plane wave)
Triple Slit (plane wave)
Doppler Effect
Beats
Something else you find really interesting
You have two options for completing this assignment:
· Make small (about 4 in. x 4 in.) sketches with colored pens/pencils…OR…
· Use a “screen capture” program to copy and paste the actual images from the applet window into a document (MS Word with text boxes, for example), which can then be saved and printed.
You can download a free trial version of an easy to use screen capture program at http://www.etrusoft.com/. The image shown on this handout was “captured” using this program.
Another option is to use the “print screen” function on the keyboard and then paste the picture in your report. Pressing “print screen” (Prnt Scrn) on the keyboard copies the entire screen, so you may want to enlarge the ripple tank window to fill the entire screen.
You can probably fit 6 diagrams/sketches on each side of a page. Be sure to label each sketch.

Assalamualaikum...cikgu, sy baru sahaja ditugaskan utk mengajar fizik di sebuah sklh luar bandar di Sarawak.n i'm really curious on what is actually the best method to teach physics . of cuz, ms dlm kursus pendidikan dl dh belajar. tp bkn spt realiti yang disangkakan. dan sy sgt2 ingin tahu mengenai PEKA. sklh sy ada dua org sj guru fzk. sy ditugaskn utk mngajar form4, dan sorang lg mngajar form5.so,, stlh sy tjumpa blog cgu ini, sy sgt teruja n i hope i can contect u. how cai i contact u. well, can u reply me via email. hurun_eini@yahoo.com. syukran.
