2. Eye & Retina

how do we go from the distal stimulus to the proximal stimulus with visual perception?

what is light?

what is a wavelength & intensity?

how do we psychologically experience wavelengths & intensity?

what is the measurement/units of the position of wavelengths we're sensitive to?? i.e. visible light

what are the colours for short, middle & long wavelengths?

how does light help us perceive the distal stimulus? (proximal stimulus)

what is the function of the eye?

where are receptor cells located? what're they called? (specialisation)

Which parts of the eye form an edjustable aperture?
