Answer:
1 Sight, or Visible Light, generally refers to electromagnetic radiation that can be seen in the human eye. ... Light can also be defined in terms of a stream of photons, a massless packet of energy, each moving with wavelike properties at the speed of light.
2 The location where the optic nerve attaches to your retina has no light-sensitive cells, so you can't see anything in it. This is the blind spot.

4 Rod cells act as specialized neurons that translate sensory stimuli in the form of photons (light particles) to chemical and electrical stimuli that can be processed by the central nervous system.
Cone cells, or cones, are one of the two groups of photoreceptor cells in the retina of the eye and are responsible for both color vision and color sensitivity of the eye; they work well in very bright light, similar to rod cells that work more in dim light.
