Reflection
This is what the light ray is called once it reflects off a mirror.
What is reflected ray
True or False: The angle of incidence of a light ray is equal to the angle of refraction
What is false
This part of the electromagnetic spectrum is what we can see.
What is the visible spectrum
The three primary colors of light are
What is red, green, blue
In mirrors, the point where light rays reflect back and converge at a single point
What is the focal point?
This is the light ray that first hits the mirror
What is the incidence ray
This is a measurement of how much light slows down in a substance
What is refractive index
Name all the colors of the visible spectrum
What is ROYGBIV
Electromagnetic waves vary depending on
What is frequency and wavelength?
an image formed when rays of light actually pass through a point on the image, and can be projected onto a screen
What are real images?
If the angle of incidence is 54 degrees, the angle of reflection will be?
What is 54 degrees
This is the refractive index of air
What is 1.0003
This type of electromagnetic radiation is responsible for the sunburns or damage to biological tissue we experience when we're in the sun too long.
What is UV radiation
light can be filtered so that all waves are parallel to each other through
What is linear polarization?
The process of separating polychromatic light into its component wavelengths
What is dispersion (and diffraction)
This is the type of reflection that happens when a light ray hits a smooth surface
What is specular reflection
The equation: ni sin(angle of incidence) = nr sin(angle of refraction)
What is Snell's law?
This type of electromagnetic radiation creates images of our bones on films
What is X-rays
This model of color explains what is produced when different colours of light are mixed together
What is the additive model of color
An upright pencil is placed in front of a convex spherical mirror with a focal length of 8.00 cm. An erect image 2.50 cm tall is formed 4.44 cm behind the mirror. Find the position of the object, the magnification of the image, and the height of the pencil.
Do = 10 cm, M = 4.44, h= 5.62 cm
This is the type of reflection that occurs when light rays hit an uneven surface (i.e. side of a mountain)
What is diffuse reflection
The refractive index of air is 1.0003 and the refractive index of crown glass is 1.52. If an incoming ray of light hits the glass from air at an angle of 25 degrees, then the angle of refraction is
What is 16.15 degrees?
This type of radiation is also a common way that we heat our food
What is microwaves
This model of color explains why objects are the color they are based on the light that is absorbed and reflected by an object's pigments.
What is subtractive model of color
