Physics: Properties of Light

Study Notes

Light is a form of electromagnetic radiation that is visible to the human eye.
It is a type of energy that travels in the form of electromagnetic waves.
Light has both wave-like and particle-like properties, exhibiting characteristics of both in different situations.

Wavelength: The distance between two consecutive peaks or troughs of a light wave, measured in nanometers (nm).
Frequency: The number of oscillations or cycles of a light wave per second, measured in hertz (Hz).
Speed: The speed of light in a vacuum is approximately 299,792,458 meters per second (m/s).
Amplitude: The maximum displacement of a light wave from its equilibrium position.

Visible Light: Electromagnetic radiation with wavelengths between 400-700 nm, perceived by the human eye as different colors.
Infrared (IR) Light: Electromagnetic radiation with wavelengths longer than 700 nm, perceived as heat.
Ultraviolet (UV) Light: Electromagnetic radiation with wavelengths shorter than 400 nm, not visible to the human eye.
X-Rays and Gamma Rays: Electromagnetic radiation with very short wavelengths, used in medical imaging and other applications.

Reflection: The change in direction of light when it hits a surface and bounces back.
Refraction: The bending of light as it passes from one medium to another with a different optical density.
Diffraction: The bending of light around an obstacle or through a small opening.
Absorption: The absorption of light energy by a material, converting it into other forms of energy.

Vision: Light is essential for human vision, allowing us to perceive and interpret our surroundings.
Photography: Light is used to capture images and create photographs.
Communication: Light is used in fiber optic communication systems to transmit data over long distances.
Energy: Light is used to generate energy through solar panels and other technologies.
