1. An X-ray photon carries 1 keV of energy, while a visible-light photon carries 3 eV. Regarding these two photons, which statement is NOT correct?

The X-ray photon has a shorter wavelength than the visible photon

The two photons carry clearly different amounts of energy

The two photons travel at different speeds through a vacuum

The X-ray photon has a higher frequency than the visible photon

All photons, regardless of their energy or wavelength, travel at exactly the same speed through a vacuum — the universal speed of light. Claiming their speeds differ is the incorrect statement here.
