What type of electromagnetic waves did Maxwell predict before their experimental discovery?
**Radio waves** λ≈10⁻¹ to 10⁴ m, f≈10⁴ to 10⁹ Hz, produced by rapid acceleration/deceleration of electrons in aerials/antenna, used for long-distance communication because low frequency diffracts around obstacles and reflects from ionosphere, enabling ground wave and sky wave propagation, effective for broadcasting. The document mentions that Maxwell predicted the existence of electromagnetic waves, which were later confirmed to include light, radio waves, and others, but initially, they were general EM waves. Using c = fλ, E₀/B₀ = c, I_d = ε₀ dΦ_E/dt, and spectrum classification λ = c/f, eval
