Flashcards
Planck's Quantum Theory
Planck's Quantum Theory
Energy is quantized, meaning it can only exist in discrete packets called quanta. The energy of each quantum is directly proportional to the frequency of the radiation.
Planck's Law
Planck's Law
The energy of electromagnetic radiation is directly proportional to its frequency, and inversely proportional to its wavelength. Higher frequency waves, having shorter wavelengths, carry more energy.
Speed of Light Equation
Speed of Light Equation
The speed of light is a constant value and is related to frequency and wavelength. The speed of light is the product of frequency and wavelength, and can be used to calculate their values.

Study Notes
Quantum Theory
- There is always a central point in quantum theory.
Heliocentric vs Geocentric Models
- Heliocentric Model - Sun centered
- Geocentric Model - Earth centered
Planck's Law
- c = 2πf
- λ = c/f
- f = c/λ
Electromagnetic (EM) Waves
- Frequency - vibrations (Hertz)
- Energy - Watts /Boltz
- Wavelength - seconds / minutes /time
Different Types of Waves
- Radio Waves - AM, FM
- Micro waves - Oven
- Infrared Waves - Night vision goggles
- Visible Light - Sunlight, flashlights, light bulbs
- Ultraviolet - Sunlight
- X-rays - airport scanners, human x-rays, detect elements
- Gamma rays - brain disorders, tomography, PET Scan
