Light Spectra
This kind of invisible light wave can be seen with heat vision goggles and its spectrum is just below the visible spectrum. Some animals can see these rays!
Infrared
This type of mirror reflects parallel lines toward each other and can produce real, upside-down images, and virtual, right-side up images.
Concave Mirror
These lens are wider in the middle than at the sides. They correct far-sightedness.
Bioluminescence
This part of the eye controls the size of the pupil.
Iris
These light waves are used in wireless technologies like Wi-fi and cellular telephones
Radio waves
This type of mirror causes parallel rays to diverge, but does render a virtual image with a wider field of view. Good for bus and truck drivers alike!
Convex Mirror
These types of lenses are used to correct myopia
Concave lenses
Incandescence
This model of colour describes how substances that absorb different wavelengths of light will produce different colours when mixed.
Subtractive model of light
These waves have the smallest wavelength. Look out, cancerous cells!
Gamma waves
Light rays moving from a medium of lower density to higher density will bend this way in reference to the normal.
Toward the normal.
This triangular prism of crystal or other translucent material splits white light into its constituent colours.
L.E.D. stands for these three words.
Light Emitting Diode
This colour of light is produced when mixing green and red light
Yellow
These waves are just above the visible light spectrum and cause specific chemical substances to fluoresce (absorb these waves and emit visible light).
Ultraviolet waves
The law of reflection states that these two types of angles are equal in the same plane as the normal.
Concave lens cause light to do this.
Diverge
LEDs use this type of luminescence
Electroluminescence
This type of vision problem causes light to be focused in front of the retina, rendering the image more blurry the further away the object is.
Near-sightedness or myopia
These three types of waves are dangerous to living cells and are called "ionizing radiation".
UV, Xray, and Gamma waves
A water droplet can act like this type of lens (it is generally spherical)
convex.
LEDs have supplanted other kinds of light technologies because they use less electricity. In other kinds of bulbs, a lot of the energy was converted to this type of energy instead of light, making them less efficient.
Heat or thermal energy
This two word term describes the way light travels in straight lines unless passing through a different medium or contacting a particle of matter.
Rectilinear propogation
