What is reflection?
It's the two characteristics that light is said to behave as when describing its duality.
What are waves and particles?

What are X-rays?
"It's a bird! It's a...." word that describes the type of mirror that's producing the virtual, upright, unmagnified image of this superhero's likeness.

Category: Particle-like Behavior
This two-word term refers to the minimum amount of energy required to remove an electron from the surface of a metal.

It's the type of field that runs perpendicular to the electric field in a light wave.
What is a magnetic field?
The "water on the road" mirage is due to hotter air above the blacktop, causing this bending of light rays.

What is refraction?
When an atom undergoes a quantum leap, one of these light particles is emitted or absorbed.
What is a photon?
Stations like this convert this form of light wave into mechanical sound waves for the pleasure of their listeners.

What are radio waves?
It's what θ2 represents in this image.

What is the angle of refraction?
While mechanical waves depend on this matter-filled region to travel through, light waves can travel with or without it.
What is a medium?
Light is demonstrating this wave behavior to produce the patterns shown.

What is interference?
It's the name of this phenomenon that demonstrates light's particle-like nature.

What is the photoelectric effect?
Not only is it the type of light you emit as body heat, it's also the light television remote controls emit.
What is infrared, (or IR).
It's the type of light manipulating device shown here, as well as the type of image it's producing.

What are a convex lens (or convergin lens) and a real image?
It's what the "e" and the "E" respectfully stand for in this image.

What are electron and energy?
The image below reveals that when it comes to this behavior of waves, the size of the gap matters.

What is diffraction?
The results of this experiment demonstrate light's wave-like nature.

What are gamma rays?

The shirt's pigments absorb (subtract) this color and reflect these two to produce its magenta hue.

He put forth the equations that helped further describe the electromagnetic waves that Faraday had proposed years earlier.

Who was James Clerk Maxwell?
It is either of the two adjectives that distinguish the mirror images shown in the bodies of water depicted here.

What are diffuse, and specular reflections.
The field of quantum mechanics was ushered in as Max Planck solved this crisis in physics where classical theory incorrectly predicted that an ideal black body would emit infinite energy.
What is the ultraviolet (or UV) catastrophe?
Finding that a nearby magnetron had melted a candy bar in his pocket led Percy Spencer to invent this

Defined as the ratio of the speed of light in a vacuum, c, to its speed in a particular medium, v.
n = c/v
