Eye Need You To Answer
This structure controls the amount of light entering the eye
Iris
This type of telescope contains mirrors and a lens
Reflecting telescope
This type of radiation we can 'see' as heat
infrared radiation
An object that emits light is called this
luminous
These are the 4 properties of light
Light bends (refracts), is a form of energy, can reflect, moves in straight lines
Concave lenses will fix this type of vision problem
Nearsightedness
light passing through substances with different densities will do this
Refract
This type of radiation passes through skin and muscle tissues
x-rays
When an object lets all the light through
Transparent
This states that the angle of reflection must always equal the angle of incidence
The law of reflection
Vertebrates have camera eyes, but most insects have this type of eye
Compound eye
This kind of mirror does not form a focal point
Convex mirror
This type of radiation has the shortest wavelength
Gamma rays
This mathematition thought that light came out of the eyes to see
Pythagoras
This type of reflection occurs on rough surfaces, that do not create a glare
diffuse reflection
In a camera, this structure acts the same as the pupil
Aperture
When light passes through this object, light will be directed to a focal point
Convex lens
Visible light is in between these two sections of the electromagnetic spectrum
Infrared and ultraviolet
The light an animal produces
Bioluminescence
Following the The Subtracting Colours Model, if only the red rays are reflected to your eye, the object will appear this colour
Red
These are found in the retina. Rods and cones are the two types
photoreceptors
Information of what we see travels to the brain through this
The optic nerve
This type of radiation has the second longest wavelength
microwave rays
This layer is found behind the retina in some animals, acting like a mirror to keep the light in the eye longer
tapetum lucidum
The secondary colours of light
Yellow, cyan, magenta
