Study Notes
Light and its Dual Nature
- Light exhibits both wave-like and particle-like properties, a concept called wave-particle duality.
- The Double Slit Experiment demonstrates light's wave nature. When light passes through two slits, it creates an interference pattern, indicating wave behavior and interaction.
- The Photoelectric Effect showcases light's particle nature. Light striking a metal surface releases electrons, suggesting light exists as discrete energy packets called photons.
Properties of Light
- Light travels as a transverse electromagnetic wave.
- Light travels in straight lines called rays.
- Light can travel in a vacuum, as it consists of fields, not requiring matter to propagate.
- Light travels at an incredibly fast speed, approximately 300,000,000 m/s in a vacuum.
- Light can be reflected when it encounters a smooth surface, bouncing back.
- Light undergoes refraction when entering a new medium, changing its speed and direction.
- Light can be dispersed into its constituent colors when passing through a prism.
- Light exhibits diffraction, bending around edges or passing through slits.
- Light interacts with materials in various ways: reflection, transmission, and absorption.
