2.Reflection & Refraction of light
Can you see it?
Disorder and light types
100
It contains millions of light-detecting cells called rods and cones
Retina
100
A ray of light, or other wave, that strikes or falls upon the surface of an object is called?
Incident Ray
100
The amount of bending in refractions depends on the Angle of incident ray and the ______________.
Change of speed
100
Dark colours __________ more light than light colours
absorb
100
A laser is an example of ____________ light.
Coherent Light
200
The black opening in the center of the eye's iris that controls how much light enters
pupil
200
The beam of light (or other wave) that bounces off a surface after hitting it, is called?
reflection ray
200
If a light beam starts in water and exits to air the light beam will ___________ in speed?
increase
200
___________________ is a material that allows light to pass through completely.
transparent
200
A light bulb is an example of _________________.
Incoherent Light
300
the clear, dome-shaped outer layer at the front of the eye.
Cornea
300
The bending of light as it passes from one transparent substance into another, is called?
refraction
300
___________ states that the angle of reflection equals the angle of incidence.
Law of Reflection
300
A ______________ is a material that allows some light to pass through, but not all light.
Translucent
300
___________ is when our eyes have misalignment errors
Binocular Vision Dysfunction
400
The photoreceptors that work best in low level of light. There are over 100 million in one eye.
rods
400
An it is an imaginary line, strictly perpendicular line (90 degree) drawn at the exact point where a light ray hits a surface
Normal Line
400
A higher _____________ means the light slows down and the light will bend towards the normal line
refractive index
400
An ____________ is a material that does not let any light pass through. We cannot see through these objects at all
opaque material
400
_____________ Caused by weakness in the muscles that move our eyes. The result is a cross-eyed look as the person cannot align the eyes in the same direction at the same time.
Strabismus
500
photoreceptor cells in the eye's retina responsible for color vision and sharp, high-acuity daylight vision
Cones
500
what is the reflection angle 
41 degrees
500
If a light beam starts in water and exits to air the light beam will move ____________ from the normal line?
away
500
A ________ is a natural optical illusion where light bends through layers of air with different temperatures, creating a false reflection
mirage
500
A type of poor vision that usually happens in just one eye. Symptoms are an eye that wanders inward or outward.
Amblyopia
