I don’t see her exact list, but the usual mistake is confusing wavelength with energy (or misreading “weakest” as intensity). Commonly students reverse the order because they think longer wavelength = “stronger.”

Key points and the correct ordering (weakest → strongest in photon energy):
- Radio waves < Microwaves < Infrared < Visible (red → ... → violet) < Ultraviolet < X‑rays < Gamma rays

Why: E = hf and f = c/λ, so photon energy E ∝ f ∝ 1/λ — longer wavelength means lower energy. If by “weakest” she meant lowest intensity (power/brightness), that’s not an intrinsic property of the wave type but depends on the source, so the question would be ill‑posed.

Also note: the X‑ray vs gamma distinction is sometimes made by origin (atomic/nuclear) rather than strict energy, so their boundaries can overlap. If you paste her list I’ll point out exactly where she went wrong.
