(Types of Light)
(Types of Light)
This type of light is produced when an object is heated until it glows, like in a traditional light bulb.
What is incandescent light?
The speed of light in a vacuum
What is 3 x 108 m/s?
The angle of this is equal to the angle of reflection.
What is the angle of incidence?
This is the name of the ratio of the speed of light in a vacuum to the speed of light in a given medium.
What is the index of refraction?
The element that would have the fewest ranges of electromagnetic emissions, due to having the fewest structures to emit them.
Hydrogen - having only one electron to excite!
This type of light is produced by living organisms, like fireflies or deep-sea creatures.
What is bioluminescent light?
This type of wave has the longest wavelength and is used in communication like radio broadcasts.
What are radio waves?
At least this many light rays need to meet in order for an image to be located.
What is two?
This is the effect where light splits into its component colours, as seen through a prism.
What is dispersion?

Daily double! Make your wager!
The unit and approximate value range in which we measure the ranges of visible light
This type of light is produced through a chemical reaction, commonly seen in glow sticks.
What is chemiluminescent light?
This is the name for the range of the electromagnetic spectrum that humans can see with their eyes.
What is visible light?
This type of curved mirror is used to magnify an image, such as in a makeup mirror.
What is a concave mirror?
Describe the equation determining the index of refraction in a given medium.
n = c/v
Mr. Zaslavsky's favourite element to show electromagnetic band emission spectra
Probably neon
This type of light is created by certain substances that absorb energy and slowly release it as light, often glowing in the dark.
What is phosphorescent light?
This type of wave has the shortest wavelength and the highest energy on the electromagnetic spectrum.
What are gamma rays?
At this point in a concave mirror, no image is produced.
What is the focal point?
When light passes from water to air, it bends in this direction relative to the normal.
What is away from the normal?
The century in which 'scientists' began describing light with mathematics
The 17th century (1600s)
This type of light is generated when electricity excites a gas, like in neon signs.
What is fluorescent light?
This type of radiation is used in heat-seeker missiles.
What are infrared rays?
This type of mirror spreads out light and is used in car side-view mirrors to give a wider field of view.
What is a convex mirror?
This is the name for the phenomenon where light bends so much it reflects entirely within a medium.
What is total internal reflection?
The "natural philosopher" that wrote "Opticks: or, A Treatise of the Reflexions, Refractions, Inflexions and Colours of Light"
Sir Isaac Newton
