Quantum theory

Quantum Theory

By: Lucas, Steven, Brandon and Kristen


Vocabulary

Vocabulary

  • 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.


Vocab cont

Vocab cont…

  • 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.


Properties of light

Properties of light

  • 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.


Blackbody radiation

Blackbody radiation

  • 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.


Max planck

Max Planck

  • 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


Planck s constant and postulate

Planck’s constant and postulate

  • 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.
