Characteristics of Light
Includes radio waves, visible light waves, and x-rays
What is the electromagnetic spectrum?
Should reflect around 90% of incoming light
What is a mirror?
Type of curved mirrors used to magnify an image
What are concave spherical mirrors?
Red, green, and blue
What are the additive primary colors?
Measurement unit of the rate of light's emittance
What are lumens (lm)?
Can be specular or diffuse
What is reflection?
Equal in value to a mirror's center of curvature
What is the radius of curvature?
Cyan, magenta, and yellow
What are the subtractive primary colors?
An electromagnetic wave's two oscillating fields
What are electric and magnetic fields?
Type of image always formed by flat mirrors
What is a virtual image?
When reflected light rays from a spherical mirror do not intersect at the image point
What is spherical aberration?
The process of separating an electromagnetic wave's electric-field oscillations
What is linear polarization?
Luminous flux divided by the area of an illuminated surface
What is illuminance?
Illustrations meant to determine the location of a mirror's formed image
What are ray diagrams?
The ratio of image height to object height
What is magnification?
The line along which transmission polarization occurs
What is the transmission axis?
Analysis of waves named after Christiaan Huygens
What is Huygens's Principle?
Equal in value to the angle of reflection
What is the angle of incidence?
Types of mirrors that do not experience spherical aberration
What are parabolic mirrors?
Polarization via absorption and re-radiation of light by atmospheric particles
What is scattering?
