Double-Slit Experiment using water

Click For Summary
SUMMARY

The discussion confirms that conducting a double-slit experiment with water waves is feasible, particularly by using two point sources such as stones or rods. Observing wave interference in a controlled environment, like a turtle pond, is possible by creating a barrier with two openings and exciting waves on one side. The challenge lies in scaling the experiment and managing the rapid attenuation of water waves. Techniques such as using an electric motor to dip rods into the water can facilitate steady wave observation.

PREREQUISITES
  • Understanding of wave interference principles
  • Basic knowledge of water wave behavior
  • Familiarity with experimental setup techniques
  • Experience with wave observation methods
NEXT STEPS
  • Research methods for observing water wave diffraction and interference
  • Explore the use of electric motors for wave generation in experiments
  • Study the effects of wave attenuation in water
  • Learn about experimental design for wave physics demonstrations
USEFUL FOR

Students of physics, educators conducting wave experiments, and hobbyists interested in practical applications of wave interference principles.

Homework Statement



Would it be possible to do a double-slit experiment for water waves? Can you observe wave interference in the turtle pond on campus?

Homework Equations





The Attempt at a Solution


I feel that since water waves are in fact waves, they can no doubt interfere with one another. However, I am not certain that the results for the double-slit experiment would be similar to those when using light. I have absolutely no idea why though. Any help is greatly appreciated. Cheers.

The big difficulty is scaling the experiment, and observing the rapidly attenuated waves on water.

You can certainly observe the diffraction/interference from a single slit with water waves.
 
Just throw in two stones at the same time. You get two point sources with radially spreading waves. Where the wave fronts meet you can see interference.

If you want to be fancy, use some kind of electric motor to dip two rods into the water periodically. That way you will eventually get to a steady situation that is easier to observe. In particular it is easier to compare amplitudes at different positions.

If you really want a double slit experiment, then put a barrier with two openings across your pond/bath/whatever. Excite waves on one side (does not matter how) and observe on the other side.
