Term
What is the shortest wavelength of color? The longest? 

Definition
violet is shortest. red is longeest 


Term
What equation relates the speed of light to frequency and wavelength 

Definition


Term
What is the visible spectrum for humans? 

Definition


Term
convex mirrors vs concave mirrors 

Definition
 diverging mirrors, the center of curvature and the radius of curvature are behind the mirror
 converging mirrors, the center of curvature and the radius of curvature are in front of the mirror



Term
How is focal length related to the radius of curvature for spherical mirrors? 

Definition


Term
what is the equation for magnification? 

Definition
m = i/o
m is magnification, it is dimensionless
i is the distance between the mirror/lense and the image
o is the distance between the object and the mirror/lense
A negative magnification signifies an inverted image
A positive value signifies an upright image 


Term
What equation relates the distances between image, object, mirror/lense and focal point? 

Definition


Term

Definition
If an image is in front of the mirror it will have a positive distance and is real. If an image is behind the mirror it will have a negative distance and is virtual. The convention is the opposite in lenses. The real side is where the light rays are reflected or refracted and where the image should be 


Term

Definition
states that there is an inverse relationship between the index of refraction and the sine of the angle of refraction

Term
How can you determine the speed of light when it isn't in a vacuum? 

Definition
n = c/v
n is the index of refraction, dimensionless
c is the speed of light in a vacuum, m/s
v is the speed of light in the medium, m/s 


Term
What is the critical angle and how can it be determined? 

Definition
the critical angle is when the refracted angle equals 90 degrees, when the angle of incidence is greater than this angle a phenomenon in which all the light incident on a boundary is reflected back into the original material, this is called total internal reflection
θ_{c} = sin^{1}(n_{2}/n_{1})
θ_{c} is the critical angle
n_{1} is the medium the light ray starts in
n_{2} is the medium the light ray is going into 


Term
What is the equation to be used when the thickness of a lens can't be ignored? 

Definition
[image]
n is the index of refraction of the lens material
r_{1} is the radius of curvature of the first lens surface
r_{2} is the radius of curvature of the second lens surface 


Term

Definition
P = 1/f
P is in diopters
P is positive for a converging lens and negative for a diverging lens 


Term
How to determine focal length, power and magnification in multiple lens systems 

Definition
 1/f = 1/f_{1} + 1/f_{2} + 1/f_{3} + ...
 P = P_{1} + P_{2} + P_{3} + ...
 m = m_{1} + m_{2} + m_{3} +...



Term

Definition
all of the light rays have electric fields with parallel orientation in this kind of light 


Term

Definition
the bending and spreading out of light waves as they pass through a narrow slit
