Handylearn Wavelabor

Thử nghiệm với sóng mô phỏng, và màn hình hiển thị hình ảnh động đầy màu sắc.

Experiment with simulated waves, and display colorful animations.

You can explore countless different animations by changing wave length, the speed and the color scheme.

At the bottom there is a amplitude-graph which displays the change of the amplitude in time. You can observe the characteristic sinus waves there.

Physical background: We all know what water waves are. Physicists also say that light is a wave, and even matter sometimes behave like a wave. This has some consequences we should look at.

In our Wavelabor, the slider controls the wavelength. You can switch between two light sources or use them together.

If you use both light sources together, you get something which is called interference. Please notice that some spots of the picture are not changing. You can see this best if you use the “rainbow” color theme: there are some green lines that stay green. But because a wave only exist if it changes, in these spots the wave disappears! So, sometimes light and light leads to darkness!

App-Rights: the app can create images of the simulation and stores them. It need storage access rights for this. No other rights are needed.
