  2. 3. the fact or phenomenon of light, radio waves, etc., being deflected
  3. 6. is relating to electromagnetic radiation with wavelengths shorter than visible light.
  4. 8. the angles that occupy the same relative position at each intersection where a straight line crosses two others.
  5. 11. is any lens that has an inward curve in the middle. In other words, the edges of the lens are thicker than the middle.

  8. 15. intersecting a system of lines.
Down
  1. 2. Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation.
  2. 4. ternate_exterior_angles are defined as twoexterior angles on opposite sides of a transversal which lie on different parallel lines. Parallel lines cut.
  3. 5. the action or process of magnifying something or being magnified, especially visually
  4. 7. a beam of light
