Properties of Light
Light is this type of wave.
What is electromagnetic wave?
What are the three colors of light that, when mixed together, create white light?
What is additive primary colors? or What is red, green, and blue?
The angle of incidence equals the angle of reflection.
What is the law of reflection?
The angles of light passing through glass will be the ___.
What is same?
A lens that is thicker in the middle than at the edges and that refracts parallel rays to a focus.
What is a converging lens?
In a vacuum, this is the speed that light travels.
What is 300,000 km/s; also known as c.
The complementary color of green, blue, and red.
What is magenta, yellow, and cyan?
The idea that light takes the quickest path in going from one place to another.
What is Fermat's principle of least time?
Light travels faster through ___ ___ air.
What is less dense?
The darker part of a shadow where light rays are completely blocked.
What is umbra?
This happens to energy in visible light that is incident on glass.
What is transmitted to the other side?
The phenomenon that causes the sky to be blue.
What is the scattering of light from atoms and molecules in the atmosphere?
Light is incident on a smooth surface and the reflected ray all lie in the same plane.
What is specular reflection?
Refraction causes pools of water to seem more shallow or deep?
What is more shallow?
The property of materials to pass light in straight lines without being scattered.
What is transparent?
When a material absorbs the light waves that incident upon it, it will cause the material to become ____.
What is warmer?
When the sunlight travels through more of the atmosphere at sunset and sunrise than it does at noon, only the lower frequencies of visible light make it to the observer. This causes the sky to appear _____.
What is reddish-orange?
Light is incident on a rough or granulated surface and is reflected in many directions.
What is diffuse reflection?
The ____ of the light ray as it travels through glass is not the same as when it enters or exits the glass.
What is angle?
An image formed by light rays that do not converge at the location of the image.
What is a virtual image?
The amount of the electromagnetic spectrum that visible light makes up.
What is one-millionth of 1%?
This happens to light when it falls on a material that has a natural frequency above or below the frequency of the light.
The fraction of light shining straight at a piece of clear glass is reflected from the surface.
What is 4%?
A mirage is the result of this phenomenon.
What is refraction?
An energy-carrying wave emitted by a vibrating charge (often electrons) that is composed of oscillating electric and magnetic fields that regenerate one another.
