Imaginary numbers are useful tools that help solve difficult math problems. In electronics, equations that describe AC circuits make use of imaginary and complex number math. Physicists use complex numbers when dealing with electromagnetic waves, which combine properties of electricity and magnetism.

WebSo, an electric field of the form E ( z, t) = E 0 e i ( k z − ω t + ϕ 0) + c. c. = 2 ⋅ E 0 cos ( k z − ω t + ϕ 0) indeed describes a real/physical wave. Of course, while doing the maths it may become cumbersome to carry around the c.c. term through a series of equations, and so it is dropped (but implicitly, it is still there). Web1 de nov. de 2024 · which may seem true, but you have to remember the context where these imaginary numbers are used.
