There isn't a single "scientific name" for light. It depends on what aspect of light you're interested in. Here are some options:

* Electromagnetic radiation: This is the most general term, as light is a form of electromagnetic radiation.

* Visible light: This specifically refers to the portion of the electromagnetic spectrum that humans can see.

* Photon: This is the fundamental particle of light, a quantum of electromagnetic radiation.

So, depending on the context, any of these terms could be considered the "scientific name" for light.
