We recently did a lab activity that involved the use of Ripple Tank to
study various properties of waves. This was a completely new activity for us,
since we had never done anything like this before. The aim was to determine the
different effects produced by waves in water. First part involved set-up. We
were shown various parts of the apparatus and then the whole thing was put
together in front of us, with detailed explanation of each part and its usage.
We moved on to use the apparatus and see what it was like to send
ripples through water and what kinds of effects are produced. We were made to
understand the wavelength and frequency of the wave we were generating. The
waves were displayed under the tank, on a white paper. This made the
understanding a whole lot easier. With the help of obstacles, we created
external disturbances to the wave and studied the different phenomena: Reflection,
Refraction, and Diffraction. Practical demonstration of the wave theory could
not be made simpler and fun at the same time!
