What is this tool and how is it used to study light?

In summary, the conversation is about a photo that shows a kit called Laser Refraction Tank, which is used to study light from glass to air. The material of the kit could be glass, plastic, or any other liquid. The photo also shows a protractor in the background, and the tool is called a semicircular prism. It is easier to study light using a semicircular prism compared to a rectangular prism, as the light from the source is undeflected. The kit allows for easier exploration of total-internal reflection as well.

Hi!
I'm doing a light research project and to have a refraction and reflection ( I don't know if it's like this in eglish) visual representation I came up with this photo. I don't know the name of this tool and also what is it made of? In my opinion is just a glass but I don't really know. Thanks!

What nice about the semicircular prism is that you can more easily study light from glass to air (compared to a rectangular prism).
From the semicircular side, aim the light source at the origin of the semicircle (the midpoint of the straight edge).
Since the normal direction at the semicircular interface is radial, the light from the source is undeflected (as is evident from the photo)...
so that one just has to handle the rays at the flat glass-to-air interface (as opposed to two or more sets using a rectangular prism).
One can explore total-internal reflection more easily.
