Gravity & Light Flashcards
What did Isaac Newton do?
Isaac Newton proved/derived Keplers laws from the Laws of Gravity in a mathematical manner.
How does Newton’s discovery of gravity relate to Kepler’s laws?
If an object moves far enough away, the gravity felt changes. This naturally creates Kepler’s laws.
What did Newton discover about light?
Colors from prisms is in the light, not the prisms.
Photon
The smallest amount of light (pure energy)
Red Photons: More or Less Energy
Less Energy
Blue Photons: More or Less Energy?
More Energy
What type of energy has a shorter wavelength?
Higher Energy; Bluer
What type of energy has a longer wavelength?
Lower Energy; Redder
What did William Herschel do?
Discovered Infrared Light !!
Discovered Uranus
Discovered Four Moons [Oberon, Titania, Enceladus, & Mimas]
Electromagnetic Spectrum: What is the relationship between Energy and Wavelength?
Inverse; Opposites of One Another
As one increases, the other decreases.
