Numbers
What n equals
What are the indices of refraction?
Determines the color of light
What is frequency?
2 conditions for refraction
Change in speed
has to hit at an angle
How is a mirror made
What is a piece of flat glass with aluminum painted on the back
What are cones?
3x10^8
What is the speed of light in a vacuum?
C for a speed of light problem
V for a frequency problem
A yellow banana absorbs
What is Snell's law
n1sinθ1= n2sinθ2
Remember to take inverse to find just θ
θ = angles
You can't see your reflection in a piece of white paper with the reasoning being that the surface isn't smooth enough so light reflects at random angles
What is diffuse reflection?
What detects brightness
What are rods?
The formula for calculating the speed of light
What is V=c/n
A yellow banana in a room with only blue light would appear
What is black?
Air to lucite = faster or slower?
1.00 -> 1.50
to draw - more straight down
What is slower ?
(the higher the index is the slower the speed)
technology that uses the fact that light hitting a boundary at an angle greater than the critical angle will reflect internally
The three types of cones
What are red green and blue?
The formula for calculating frequency of light
What is f=v/λ(wavelength)?
Find the frequency of light which has a wavelength of 7.813 x 10^-7
Use f=V/λ(Wavelength)
V = 3x10^8
What is red?
Electromagnetic radiation that humans give off all the time
What is infrared?
The coating on the back of the glass allows some light to pass through while most reflects
What is a 2 way/security mirror?
What is the iris?
What's needed to see electromagnetic radiation that humans give off all the time
What are "night vision" or infrared sensors?
Why most 50yrs up start needing reading glasses
