100
This is the speed of light through a vacuum to three significant figures.
What is 3.00 x 10^8 m/s?
100
This person proved that white light is made of all the colors of the rainbow.
Who is Sir Isaac Newton?
100
This is the name for the idea that any wave front can be considered to be made of tinier wave fronts.
What is Huygen's Principle?
100
When two crests meet this is the type of interference they create.
What is constructive?
100
These are the types of waves which will reflect according to the law of reflection.
What are all wave types?
200
This is what you must do (at the atomic level) in order to create a light wave.
What is accelerate (vibrate) an electron?
200
This is the reason a green ball is green.
What is it reflects green, absorbing the other colors?
200
This is the reason a narrow slit will diffract light better than a wide window.
What is the narrow slit is closer in size to the wavelengths of light?
200
This is what you would see on a screen if a part of a light wave was cancelled by destructive interference.
What is you would see a dark line?
200
This is the type of image formed in a convex mirror.
What is a virtual image (right side up and smaller)?
300
If it takes longer for light to travel through glass than air, this is the explanation.
What is the transmission speed is slower for denser materials?
300
This is the best explanation for the phrase "color is subjective".
What is the color of an object depends on the type of light that is hitting it?
300
Many spectrometers use these instead of prisms to disperse light into colors.
What are diffraction gratings?
300

This experiment proved that light travels in waves.

What is Thomas Young's (Double Slit) Interference Experiment?

300
This is the best explanation to explain why/when a wave will undergo refraction.
What is when it travels into a different medium it goes a different speed, therefore changing angles?
400
This is the name for a partial shadow.
What is a penumbra?
400
This is the region of the visible spectrum in which our Sun shines the brightest.
What is the yellow-green region?
400
This is how you can use your hand to produce diffraction fringes.
What is hold your fingers really close together and look at a light source?
400

This is a good explanation of how iridescence is created in thin films.

What is light reflected on one surface is cancelled by light reflecting off the second surface. Different thicknesses cancel different colors, thus making a rainbow?

400
This is the reason that during a hot day a mirage may be seen on the ground.
What is since the air near the ground is hotter than the air above, the light waves curve up to your eyes?
500
When people say they are seeing heat waves, this is what they are actually looking at.
What is the way the light travels different speeds through different densities of air (or air of different temperatures)?
500
These are the three subtractive primary colors.
What are magenta, yellow, and cyan?
500
Laser light is considered coherent for this reason.
What is all the waves are the same wavelength, going the same direction, and they are in phase with each other?
500
This is how a hologram uses interference in order to work.
Laser light creates an interference pattern on a photographic plate when one beam arrives from an object and interferes with another that bounces off a mirror?
500
This is the reason a double rainbow is so much dimmer than a single rainbow.
What is it loses so much light out the top of each raindrop when it is reflected the second time?
