Slide 6 - Tekstslide

1.4 - Electromagnetic spectrum:
Light is a form of energy that travels in waves
The whole spectrum spans a range of waves and frequencies
Part we can see: visible part of the spectrum
Part we cannot see: infrared and ultraviolet part of the spectrum

Slide 12 - Tekstslide

1.4 - How do you see light?
Light reacts to cells in the retina.
The cells react to light and send impulses, messages, to your brain



Two different types of cells:
  • Rod cells give information on contrast, the black and white picture
  • Cone cells give information on color: red, green and blue

Slide 13 - Tekstslide

Slide 14 - Tekstslide

1.4 - Accomodation:
Accommodation: the lens changes its shape in order to see objects sharply from both far away and nearby

Slide 15 - Tekstslide

Myopia ⇒ nearsighted

You can see object nearby
Far away objects are not sharp

Hyperopia ⇒ farsighted

You can see objects far away
Nearby objects are not sharp
