When wavelength gets shorter, photon energy increases because E = h c / λ. With higher energy, photons interact less readily with matter over a given distance, so they can pass through more material before being absorbed or scattered. This means penetrating power grows as wavelength decreases. The other options don’t fit this fundamental relationship: energy isn’t reduced, isn’t unchanged, and isn’t inherently unpredictable—the trend is a clear increase in penetration with shorter wavelength.
