Study Notes
Particle Wave Duality
- Describes the dual nature of light and matter, exhibiting both particle and wave-like properties.
- Central concept in quantum mechanics, responsible for phenomena like interference and diffraction.
Energy Quantization
- Energy is quantized, meaning it exists in discrete units, corresponding to photons.
- Photons are the fundamental particles of light and carry energy.
Photon
- A photon is the basic unit of light and electromagnetic radiation.
- They can be created and destroyed, aligning with the principles of quantum mechanics.
Electromagnetic Spectrum
- The electromagnetic spectrum includes all types of electromagnetic radiation, from radio waves to gamma rays.
- Each type of radiation has a specific frequency and wavelength.
Frequency and Wavelength
- Frequency refers to the number of waves that pass a point per second, measured in hertz (Hz).
- Wavelength is the distance between successive crests of a wave, inversely proportional to frequency.
Visible Light
- Visible light is the portion of the electromagnetic spectrum that can be seen by the human eye.
- It is a small segment between ultraviolet and infrared radiation.
Incandescence and Phosphorescence
- Incandescence is light produced by high temperatures, where objects emit light due to thermal energy.
- Phosphorescence involves materials absorbing light and re-emitting it over time.
Electric Discharge
- Electric discharge refers to the release of electric energy, often observed in phenomena like lightning or neon lights.
Bioluminescence
- Bioluminescence is a natural phenomenon where living organisms produce light through chemical reactions.
- Examples include fireflies and certain deep-sea organisms.
Luminous Objects
- Luminous objects emit their own light, distinct from those that only reflect light.
- Examples include stars and incandescent bulbs.
Energy Emission from Electrons
- When electrons transition from a high energy state to a low energy state, energy is emitted in the form of photons.
- This energy release is fundamental in processes like fluorescence and radiation.
