Study Notes
Light Definition and Characteristics
- Light is a form of electromagnetic radiation that is visible to humans.
- It is defined by its wavelength, frequency, and speed.
Basic Dimensions of Light
- Brightness perception is related to the intensity of light.
- Frequency of light is related to its color.
- Wavelength of light affects its perception, with shorter wavelengths appearing more blue and longer wavelengths appearing more red.
Electromagnetic Radiation
- Infrared radiation can transmit heat from the sun.
- Infrared radiation typically falls at a wavelength of 700 nm to 1 mm.
- Microwaves are a type of electromagnetic radiation associated with cooking applications.
Types of Waves
- Radio waves are not strongly perceptible to humans.
- Visible light has wavelengths between 400 nm and 700 nm.
Properties of Light
- The property of light related to the perception of color is its frequency.
- The elementary particle that defines light is the photon.
Perceptibility
- Wavelengths of light that are weakly perceptible to humans are typically in the ultraviolet and X-ray ranges.
