Across
- 2. A small breach on a surface
- 4. The line that marks the limits or edges of something and separates it from other things or places
- 5. A smooth surface on which regular reflection takes place
- 7. A state, or the production of a state, in which rays of light or similar radiation exhibit different properties in different directions
- 10. The electromagnetic radiation within a certain portion of the electromagnetic spectrum
- 12. The point on a wave with the greatest positive value or upward displacement within a cycle
- 14. The change of direction of a ray or a wave after bumping into a barrier or a surface
- 16. The number of complete vibrational cycles of a medium per a given amount of time
- 17. The time for a particle on a medium to make one complete vibrational cycle, or in other words, one complete oscillation. According to I.S. it is measured in seconds
- 18. The position of a point in time on a waveform cycle
Down
- 1. An attribute of things that result from the light they reflect, transmit or emit in so far as this light causes a visual sensation that depends on its wavelenght
- 3. The imaginary surface representing corresponding points of a wave that vibrates in unison
- 6. The combination of two or more waves trains moving on intersecting or coincident paths
- 8. The line perpendicular to the boundary passing through the point of incidence
- 9. A substance that makes possible the transfer of energy from one location to another, especially through waves
- 11. A space devoid of matter
- 13. A natural or artificial process that emits a visible electromagnetic radiation
- 15. The magnitude, thus a scalar quantity, of the rate of change of an object's position
- 17. The transparent optical element with flat and polished surfaces and it is mostly used to disperse light
- 18. The distance travelled by a wave in a specified context
