What is the 3D Mirage JavaScript Simulation Applet HTML 5?

It's an interactive physics simulation, specifically designed to demonstrate and explore the principles behind mirages, likely using mirrors and light ray tracing. It allows users to manipulate parameters (presumably the angle of mirrors) and observe the resulting light behavior, helping them visualize how mirages are formed.

How do I use the 3D Mirage JavaScript Simulation Applet?

The simulation allows the user to drag the arrows to change the desired angle, then release them to see the rays formed. There are also play/pause and reset buttons to control the simulation. Double-clicking the panel toggles full screen mode.

What are some potential learning goals that can be achieved using this simulation?

While the specific learning goals aren't listed, the applet likely aims to help users understand the reflection of light, the conditions that create mirages, and how angles of incidence and reflection relate to image formation.

What subjects, other than physics, can this simulation be used for?

Although created for physics, the simulation applet can also be applied to mathematics (geometry and angles), environmental science (understanding atmospheric conditions that lead to mirages), and possibly even art (understanding perspective and image creation).

Who developed this simulation?

The simulation was developed by Fu-Kwun Hwang, Fremont Teng, and lookang.

Can this simulation be embedded in other webpages?

Yes, the provided HTML iframe code allows embedding the simulation within other web pages.
