Across
- 3. It causes the separation of a wave into spectral components with different wavelengths, due to the dependence of the wave speed from the wavelength in the crossed medium.
- 6. Lying or extending across or in a cross direction
- 8. The repeated or regular way in which something happens or is done.
- 10. The line perpendicular to the boundary passing through the point of incidence.
- 11. A natural or artificial process that emits a visible electromagnetic radiation.
- 12. It is a transparent optical element with flat and polished surfaces and it is mostly used to disperse light.
- 16. Range of frequencies of electromagnetic radiations and their respective wavelengths and photon energies.
- 18. It refers to the maximum displacement of a particle of a medium from its rest position when a wave passes through it.
- 20. A smooth surface on which regular reflection takes place.
- 21. Reflection of waves or particles from a surface such that the incident rays on the surface are scattered at many angles rather than at just one angle.
Down
- 1. The electromagnetic radiation within a certain portion of the electromagnetic spectrum.
- 2. It states that every point on a wavefront is itself the source of spherical wavelets.
- 4. The ratio between the velocity of light in an empty space and the velocity in a substance.
- 5. The distance between two similar points on a wave of energy, such as light or sound.
- 7. The combination of two or more waves trains moving on intersecting or coincident paths.
- 9. It is when light waves move all the way through a material without being absorbed (this happens with transparent materials).
- 13. The number of complete vibrational cycles of a medium per a given amount of time.
- 14. The change in direction of a wave passing from one medium to another, caused by its change in speed.
- 15. The magnitude, thus a scalar quantity, of the rate of change of an object's position.
- 17. The change of direction of a ray or a wave after bumping into a barrier or a surface.
- 19. The time for a particle on a medium to make one complete vibrational cycle, or in other words, one complete oscillation.
