When professor Lavelle was talking about the oscillation of electric and magnetic fields, are both important when looking at electromagnetic radiation / light? Like what is the significance of each? I know he addressed the speed of the electric field, and it's importance in different ranges of visible light, but not really magnetic fields.

The electric and magnetic fields are nor separate entities.
Electro-magnetic radiation (light) consists of both.

As I mentioned in class it is the electric field component that interacts with charged particles such as electrons.
