Refraction for High School Science

This simulation shows the refraction of light (change of direction and speed) when it goes from one medium into another.

Instructions:

- Drag anywhere in the center semi-circle to change the angle of incidence.

- The refractive indices can be changed using the slider bars on the right or...

- Tap in the upper right or bottom right of the screen to display a drop-down window.

- Use the drop window for preset materials (air, water, glass, etc.)

- Use the wavelength slider bar to change the colour.

- If index 1 is higher than index 2, the "critical angle" button will appear to place the incident light at exactly the critical angle.

- "colour deviation" will show slightly different amounts of refraction for different colours.
