Study Notes

Properties of Light

Light is a form of energy that can be perceived by the human eye.
It transmits from one location to another at a finite speed, which is the speed of light.

Spectrum of Radiation

Visible light is just a small part of a vast spectrum of electromagnetic radiation.
The full spectrum includes various types of radiation, such as cosmic rays, gamma rays, X-rays, ultraviolet light, visible light, infrared light, microwaves, and radio waves.

Visible Light

White light, which can be seen by the naked eye, is a mixture of different colors across the spectrum.
This mixture can be separated into its constituent colors by passing it through a glass prism, demonstrating how light can be both a singular entity and a combination of various wavelengths.
