Visual perception

Question 1

Perception

Answer 1

the mental process of organising and interpreting sensory stimuli sent from the senses so it achieves a meaningful form

Question 2

Sensation

Answer 2

a physiological process involving sensory receptors detecting and responding to the presence of stimuli

Question 3

Sensory receptors

Answer 3

neurons that detect and respond to physical energy

Question 4

Perceptual system

Answer 4

bodily structures involved in the process of organising and interpreting a specific type of sensory stimuli so it achieves a meaningful form

Question 5

What makes up visible light?

Answer 5

The wavelengths of electromagnetic energy from 380 nanometres to 750 nanometres to which the human eye is sensitive.

Question 6

Brightness

Answer 6

corresponds roughly to the physical amplitude of light waves (waves of higher amplitude are ‘taller’ and carry more energy, causing colours to appear brighter and more intense)

Question 7

Hue

Answer 7

what we perceive wavelengths as; colour; the longer wavelengths produce blue, green, orange and yellow, the highest being red
