Image in front of a mirror with thick glass

[Fu-Kwun Hwang]

Assume there is a very thick glass (e.g. 3cm) in front of the mirror.
An object is allocated away from the glass (distance =10cm, object to glass=10+3=13cm)
The question is: where is the image of the object (distance from mirror=? cm)

The following let you play with the simulation to find out the answer.
The initial condition is the same as above.

You can change the location of the object with mouse drag and drop,
 or change index of refraction/thickness of the glass with sliders.
Click play to start the ray tracing.
Enjoy it!

Hi prof,
Error message download jar file the error is error processing your request! no .zip available
I tried to download any jar file in NTNU but always said the same message.

We just switch to a new server and some setting was not corrected.
It is fixed now. Thank you for reporting the problem.
