Across
- 2. experimentally confirmed Maxwell's theory in 1888. He generated and detected radio waves, the first type of electromagnetic wave to be observed.
- 4. Used for medical imaging, industrial inspection, and research.
- 7. laid the theoretical groundwork for electromagnetic waves, proposing that they were a result of the interaction between electric and magnetic fields. His equations predicted the existence of these waves, which could travel through space at the speed of light.
- 8. Used for cooking, communication (e.g., cell phones), and radar.
- 9. The distance between two consecutive crest on a wave.
- 10. Used for thermal imaging, remote sensing, and heating.
- 11. The type of radiation we can see, used for vision and illumination.
- 12. The number of waves that pass a given point in a second.

- 1. Discovered X-rays in 1895.
- 3. Used for communication, broadcasting, and radar.
- 5. Used for medical treatments (e.g., cancer therapy), sterilization, and research, but can be highly dangerous.
- 6. Used for sterilization, medical treatments, and tanning, but can also be harmful if excessive.
