Study Notes
Light Energy
- Light energy is a form of electromagnetic energy.
Photons
- Photons are massless particles that transmit light energy.
Production of Light
- Light is produced by hot objects through the process of incandescence.
- Incandescence is the emission of light by hot objects due to their high temperature.
Production of Photons
- The vibration or acceleration of charged particles, such as electrons, results in the production of photons.
- The energy released by these particles is converted into photons, which are then emitted as light.
