X-rays are typically used in medicine for which purpose?
**Gamma rays** λ10¹⁹ Hz, produced by nuclear transitions and radioactive decay, associated with nuclear processes because nuclear energy levels MeV vs atomic eV, highest photon energy, used in cancer treatment due to high penetration and cell damage, also sterilization, astronomy. X-rays are used as a diagnostic tool in medicine and for treating certain forms of cancer, as mentioned in the document. Using c = fλ, E₀/B₀ = c, I_d = ε₀ dΦ_E/dt, and spectrum classification λ = c/f, evaluation yields Diagnosis and cancer treatment, illustrating EM wave transverse nature and Maxwell's di
