THE LIGHT

2. The wave's point that displays the maximum amount of negative displacement
5. A phenomenon which occurs when a ray of light strikes a surface. The energy from the light is transferred to the surface material
6. The number of crests of a wave that move past a given point in a given unit of time The most common unit is the hertz (Hz)
8. A material substance (solid, liquid, gas, or plasma) that can propagate energy waves
11. The luminance of a body, apart from its hue or saturation
14. The point or part of a system where energy or mass is added to the system
16. light Electromagnetic radiation of a single frequency
17. A line (straight or curved) that is perpendicular to the light's wavefronts. Geometric optics describes how they propagate through an optical system
18. Electromagnetic radiation within a certain portion of the electromagnetic spectrum. The word usually refers to visible xxx
19. Property of waves defined as the distance between the peaks of two waves. If two waves have the same frequency,
20. Physical quantity referring to how fast something is moving

1. Property of a light wave determined by the frequency of the electromagnetic radiation
3. The spatial period of a sinusoidal wave.It is inversely related to frequency, we use the greek letter lambda (λ) to designate it.
4. A phenomenon happening when light waves move through a material without being absorbed
7. An object that reflects light. If it's flat, incident light in some range of wavelengths
9. A transparent solid body, often having triangular bases, used for dispersing light into a spectrum
10. Devices constructed to bend light. Convex ones will converge light and can form an image
12. The time for a particle on a medium to make one complete vibrational cycle. The unit of measure is second.
13. A phenomenon in which two waves superpose to form a resultant wave of greater or lower amplitude
15. The point on the medium that exhibits the maximum amount of positive
