In a physics study group, a friend says in a profound tone that light is the only thing we can see. After a few laughs, your friend goes on to say that light is produced by the connection between electricity and magnetism. Is your friend correct?
My responds is that my friend is both correct and incorrect. Am I on the right track.
Your friend is wrong. We cannot see light. if light travels through the sky, we don't see it. What your friend sees is light traveling to his eyes, only, and that only because it hits a neural receptor in his eye. All the other light passing by he does not see.

He is an idiot cause we see the reflection of light more often than not, rather than light itself
Yes, you are on the right track with your response. Your friend is partially correct in stating that light is the only thing we can see. Light is the electromagnetic radiation that is visible to the human eye. It is the only form of electromagnetic radiation that our eyes are sensitive to.
However, your friend's statement about light being produced by the connection between electricity and magnetism is also accurate. This is explained by Maxwell's equations, which describe how electric and magnetic fields are interconnected. According to these equations, when an electric field changes, it creates a magnetic field, and vice versa. These changing electric and magnetic fields create electromagnetic waves, of which light is one form.
So, your friend's understanding of light being produced by the connection between electricity and magnetism is correct.
