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!

Embed a running copy of this simulation

Embed a running copy link(show simulation in a popuped window)
Full screen applet or Problem viewing java?Add http://www.phy.ntnu.edu.tw/ to exception site list
• Please feel free to post your ideas about how to use the simulation for better teaching and learning.
• Post questions to be asked to help students to think, to explore.
• Upload worksheets as attached files to share with more users.
Let's work together. We can help more users understand physics conceptually and enjoy the fun of learning physics!

re-layout according my usual design
added second set of arrows (yellow) and dynamic text v = XXX c as it enters the medium 2
