Electro? Magnetic?
It's all radiation to me.

Lenses and mirrors and... that's it. OH MY!
Lights! Camera! Models!
The Eyes Have It
100
The type of EMR that we can see
visible
100
If the angle of incidence is 50°, then the angle of reflection is...
50°
100
What's this?
convex mirror
100
The ray model of light says that light travels in...
straight lines
100
This part of the eye does 80% of the refracting to focus light for vision.
cornea
200
Shortest wavelength of EMR
gamma rays
200
The word that means "substance light is moving through"
medium
200
What's this?
concave mirror
200
The model of light involving photons.
particle
200
The jelly-like goop inside the eye that helps keep its shape (like air in a balloon).
vitreous humour
300
longest wavelength colour of visible light
red
300
The reason that light bends when it refracts.
Moves at different speeds through different materials.
300
The type of lens that's in an eyeball
convex
300
The wave model of light could explain this phenomenon. We sort of observed it with a laser pointer and a human hair, and some people in a video observed it inside a refrigerator box.
double-slit
300
The fancy science word for nearsightedness
myopia
400
as wavelength increases, frequency...
decreases
400
True or false: when light interacts with a surface it can either reflect or refract, but not both
False. Doing both is very common.
400
The fancy science word for a flat mirror.
plane
400
The phenomenon that can only be explained using the particle model of light. Einstein got a Nobel Prize for this!
photoelectric effect
400
These are the two types of light-sensitive cells at the back of the eye.
Rods and cones.
500
the height of a wave, contributes to how the total energy of a wave without affecting its frequency or wavelength
amplitude
500
When light moves from a LESS dense material to a MORE dense material, this is how it bends compared to the normal line.
towards
500
Alternate name for a concave lens.
Diverging lens.
500
The cool sciencey term that describes how light can sometimes act like a wave and sometimes act like a particle.
wave-particle duality
500
Some animal eyes have this, it helps them see in the dark!
tapetum lucidum
