What have we learnt so far?
•Why do you think people believed in a geocentric
universe?
•Why did people not want to accept a heliocentric
universe?
•Why was a heliocentric universe a better
explanation for retrograde motion?
•Modern scientists don’t believe in a geocentric or
heliocentric universe, what do they believe in
instead?

system (h)
What have we learnt?
1. What did your model of the solar
system look like? Was there
anything surprising about it? (c)

of galaxies and the universe
confused, what is the difference? (b)

Refraction
The Kingfisher
Refraction
• Refraction of light is the bending of light rays at the interface of dissimilar substances
Air
Water
The Kingfisher
Refraction
•When light is passing from a higher refractive substance into a lower refractive substance the light
rays bend away from the perpendicular to the surface.
perpendicular
Air – lower refractive index
Water – higher refractive index
The Fish
Refraction
•When light is passing from a lower refractive substance into a higher refractive substance the light
rays bend toward the perpendicular to the surface.
perpendicular
Air – lower refractive index
Water – higher refractive index
Glass Window
•Light passing through a transparent material exits at the same angle it enters
Air – lower refractive index
Glass – higher refractive index
Air – lower refractive index
