Understanding Light Refraction: An Experiment with a Water Tank

Laser Refraction

We begin with a clear water tank set against a dark background to enhance visibility. Watch as we shine a laser beam at different angles into the water, illustrating how light bends when it moves from one medium (air) to another (water).

Best experiments
Thank you sir
Your experiment helps a lot in studies ❤❤

The same effect applies to battle ship rounds hitting short. They usually divert and go under the target. Those come at a very shallow angle get spun so almost never explode though might make a hole below the armour belt.

So if i want to stab a fish with a spear, I should aim slightly under where I see it?

Acute angle better than using horizontal.

Critical angle 90 where light didn't get reflect

The Canadians infected me teeth with cancers, im dying now. I need mi 100kt gold coins(size & thickness like two $2 Canadian coins ontop of each other) for each second im being exploited for mi special skills & abilities since year 2007- currently. I need payments from Canada.

OMG —- that is NOT the correct orientation for the protractor !!

The ZERO line of the protractor must be perpendicular to the air -water interface !

In refraction & diffraction the angles are MEASURED FROM THE — NORMAL !
