This is a demonstration of total internal reflection using a water tank.
This demonstration was created at Utah State University by Professor Boyd F. Edwards, assisted by James Coburn (demonstration specialist), David Evans (videography), and Rebecca Whitney (closed captions), with support from Jan Sojka, Physics Department Head, and Robert Wagner, Executive Vice Provost and Dean of Academic and Instructional Services.

Awesome. This was the perfect demonstration! Really helped me to understand the concept for my MCAT studying. Thank you!!

Thank you, this is a great demonstration. Exactly what was needed to explain to my students! I like that we can also see the laser beam refracting as it enters the water from the air.

Total Internal Reflection is happening right at the surface of the water... thats crazy.

I need to say this with a caveat because I could not do this experiment and film at the same time. Having said this, I think that I get the same results with an empty water tank turned upside down. That would mean air to air refraction. Could you confirm or infirm that? Thank you.

Can you make the critical angle on all surfaces?

What are you adding to the water to allow the laser to be visible?

Bro you can use salt as well And you can also use dust When laser beam collide with salt partical or dust partical them it will becomes visible

Does total internal reflection follow laws of reflection.

Yes in every reflection the angle of incident ray will be equal to the angle of reflected ray - hence why it looks so symmetrical
