Study Notes
Planck's Quantum Theory
- Planck's theory revolutionized physics, introducing the concept of quantized energy
- Energy is not emitted continuously, but in discrete packets called quanta
- Planck's constant (h) relates energy (E) and frequency (v) of electromagnetic radiation
- E = hv (energy equals Planck's constant multiplied by frequency)
- Planck's theory was presented in 1900 to the German Physical Society
- Planck's theory led to the development of quantum theory
- Planck later refined his hypothesis to explain the photoelectric effect
Planck's Units
- Planck length: the smallest measurable length (1.6 x 10-35 meters)
- Planck time: the shortest measurable time (5 x 10-44 seconds)
- Planck's units are fundamental units for measuring very small lengths and short durations
