Ejs Open Source Refraction Wave Model across 2 straight media java applet
author fu-kwun hwang, remixed by lookang
from here http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=152.0

for learning objectives
State that waves can change direction as they cross straight boundaries between media and that this is called refraction
Explain that refraction is caused by a change of speed in the media and use rules to predict which way the ray bends when density changes


there is another good simulation here

enjoy!

changes made include:

re-layout according my usual design
added second set of arrows (yellow) and dynamic text v = XXX c as it enters the medium 2
made medium 1 white
made drag-gable point green and remove associated slider for simpler control-layout
added hint that shows h2/h1 as the ratio of n2/n1

enjoy!
