I am sorry. There should be  images in the simulation. I forgot to upload image to the server.
I just did. You should be able to find the image when you view it next time.
You can change the arrow to change the initial direction of the light ray.

Please check out the attached files

It might be due to some bug when switching from EJS 3 to EJS4.
I just re-compiled it. It should work fine now.
Thank you!
