Refraction Applets

Introduction: Examples of refraction all around us	link	Don't let the comments put you off! (thanks Dee :)) from Youtube. 2 minutes.	3 Star
Refraction and Total Internal Reflection	link	Nice Introduction. Youtube. 9 minutes	4 Star
	link	Nice Interactice simulation	4 Star

Refraction: demonstrations
Refraction through a semi-circular glass block	link1	A 3D simulation of the refraction of light through a semi-crcular block. The angle of incidence can be varied upto and beyond the critical angle.	4 Star
	link2	An interactive teaching aid to show how light is refracted by a semi-circular block. The angle of the light source can be varied up to and beyond the critical angle.	4 Star

Refraction through a rectangular glass block	link1	A 3D simulation of the refraction of light through a rectangular block.	4 Star
	link2	An interactive teaching aid to show how light is refracted by a rectangular glass block. The optional protractor demonstrates that the incident and emerging beams of light are parallel.	4 Star

Snell’s Law	link1	Useful for demonstrating the mandatory experiment, and also for demonstrating Total Internal Reflection. Make sure to click on the "Next Scene" tab at the bottom right.	5 Star
	link2	As above, but less realistic	3 Star
	link3	Another variation	3 Star

Optical fibres
Optical fibres and nanotechnology	link	Youtube. 7 minutes. I never really understood the term 'nanotechnology' untill I saw this.	5 Star
Short demonstration of Total Internal Relflection	link	Lovely short (one minute) demonstration of TIR using a laser and stream of water from Teachersdomain.com	4 Star

Used in colonoscopy	link	Text-based, with a diagram	3 Star
	link	Click on "Colonoscopy: Inside a bottom" and navigate away	4 Star
	link	A real-time video describing the procedure of colonoscopy. Not for the queasy! From Youtube. 5 minutes	5 Star
	link	Video showing a living worm being removed from a colon. You really can find anything on Youtube. One minute.	5 Star
	link	Lou Rawls gives Damon Wayans a colon exam. Youtube comedy, one minute.	3 Star

Solving real-life problems	link	Silly stuff from Youtube	3 Star
