Enhancement to Reflection/refraction

[John M. Clement]

It would be very useful if the "flashlight/laser pointer" could be relocated above the water. In addition the ability to select several different media would be useful such as water/air, glas/air, diamond/air, glass/water ...

Let's work together. We can help more users understand physics conceptually and enjoy the fun of learning physics!

You can change the index of refraction for upper or lower media.
Click Intensity checkbox will show information about light intensity.
Select either pwave or swave for different polarization incident light.
Is and Ip are ratio of light being reflected.

If you want to download this applet (for registered user)
Please check out Intensity of reflected s-wave/p-wave and click "GET APPLET FILE" button.

I'm glad this applet is here, but I can't download it.

[Fu-Kwun Hwang]

You will be able to downliad it from Intensity of reflected s-wave/p-wave

This is a nice applet, but it appears that the wavefronts (I'm assuming that's what the thin red lines that move are when I push "Play") are moving at the wrong speed. The wavefront moves further (therefore faster) in the slow medium than it does in the fast medium. Perhaps I'm misinterpreting something?

[Fu-Kwun Hwang]

I am soory. I did not consider the wave speed in the previous version. (So the speed did not change). The code has been modified in this new version. Thank you! :-)

Hi, very nice demonstration. I'm new to this site, and don't see how to get an offline version of the applet. Please advise. Thanks.

Very nice demo! If the index n2 can be both negative and positive, it would be great to show the student for the negative refraction.

[Fu-Kwun Hwang]

Here is the version with extral options: negative n2 (if you click the "negative n2" check box, n2 will become negative.
