Quantum Theory

By: Lucas, Steven, Brandon and Kristen

- Spectra: the range of colors that a object will give off when it is heated or burned.
- Blackbody: An object that will absorb all light and can radiate it will almost no gaps in its spectrum.
- Discrete: Apart from, or separate from others of its kind.

- Quantum: a discrete amount of energy, given by the product of Planck's constant(h) and the frequency of the radiation (f)
- Empirical equation: an equation that fits the observed data but is not based on any theory
- Postulate: a claim, something said without proof of consept.

- The color of light is determined by the its wavelength.
- Increasing or decreasing the temperature of an object will change the color of the light it emits.
- Each color of light can only have a a set number of different energy levels.

- When a blackbody is heated it follows a color path until it reaches a certain temperature limit.
- The pattern stops once you reach the ultraviolet end of the spectrum.

- A German physicist that is credited with creating the founding for quantum theory.
- He won the Nobel Prize in 1918 for his work in quantum mechanics.
- Now he is known for:
1. Planck’s postulate

2. Planck’s constant

3. Planck's law of black body radiation

- He used pervious theory about blackbody radiation and experiments done with the blackbody radiation spectrum to derive this constant.
- H= 6.626 068 96 x 10^(-34) j*s
- His postulate Allows use to find the energy of light at any frequency
- E=nhv
- n is a discrete value that depends on the color of light you are dealing with, h is Planck's constant and v is the frequency.
