Light is a form of electromagnetic radiation that travels in waves, composed of photons. It’s essential for vision and carries energy.
It exhibits both particle and wave-like properties, with a spectrum ranging from visible colors to invisible ultraviolet and infrared wavelengths. Light plays a fundamental role in physics and our daily lives.
- Electromagnetic Wave: Form of energy with both electric and magnetic properties.
- Travel Speed: Moves at approximately 299,792,458 meters per second in a vacuum.
- Dual Nature: Acts as both waves and particles (photons).
- Visible Spectrum: Small portion of the electromagnetic spectrum humans can perceive.
- Propagation: Travels in straight lines unless refracted or reflected.
- Wave Properties: Exhibits interference and diffraction patterns.
- Constant Speed: Maintains constant speed in a vacuum.
- Reflection: Bounces off surfaces according to the law of reflection.
- Refraction: Bends when passing from one medium to another.
- Polarization: Can be filtered or oriented according to its oscillation direction.
