Which type of electromagnetic waves are produced by the rapid acceleration and deceleration of electrons in aerials?
**Microwaves** λ≈10⁻³ to 0.3 m, f≈10⁹ to 10¹² Hz, produced by klystron/magnetron, used in microwave ovens because frequency ≈2.45 GHz matches rotational resonance of water molecules, causing dielectric heating, also radar, satellite communication due to small wavelength allows directional beams. The document states that radio waves are produced by the rapid acceleration and deceleration of electrons in aerials. Using c = fλ, E₀/B₀ = c, I_d = ε₀ dΦ_E/dt, and spectrum classification λ = c/f, evaluation yields Radio waves, illustrating EM wave transverse nature and Maxwell's displacement current
