what are the properties and characteristic of light?
96762
The primary properties of visible light are intensity, propagation direction, frequency or wavelength spectrum, and polarization, while its speed in a vacuum, 299,792,458 meters per second, is one of the fundamental constants of nature.

The electromagnetic spectrum includes common regimes such as ultraviolet, visible, microwave, and radio waves. Electromagnetic waves are typically described by any of the following three physical properties: frequency (f), wavelength (λ), or intensity (I).

Light travels as both waves and particles through the air. When light encounters a different medium, it either reflects, transmits, or absorbs. Light reflects from minerals, which are the solid, inorganic components of rocks. Minerals are made up of crystalline structures, with many appearing as shiny crystals.

Two key points to remember about the characteristics of radiation are that X- and gamma rays are not bits of matter, they are electromagnetic wave forms possessing no charge and no mass, and they can be characterized by frequency, wavelength, and velocity.

Wavelength and frequency are the most basic properties that can be both directly and inversely related. The speed of light equation shows an inverse relationship between wavelength and frequency because as one values increases, the other value decreases.

These basic qualities of light are; INTENSITY, FORM, COLOR, DIRECTION and MOVEMENT. These are the lighting designer's tools.

Physical properties are those that can be determined or measured without changing the composition or identity of the substance. These properties include color, odor, taste, density, melting point, boiling point, conductivity, and hardness.

Physical characteristics Because most gases are difficult to observe directly, they are described through the use of four physical properties or macroscopic characteristics: pressure, volume, number of particles (chemists group them by moles) and temperature.

Understanding these four characteristics of light — quantity, quality, color temperature, and direction — won't magically make you a better photographer.

The terms light, electromagnetic waves, and radiation all refer to the same physical phenomenon: electromagnetic energy. This energy can be described by frequency, wavelength, or energy. All three are related mathematically such that if you know one, you can calculate the other two.
633798
Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity. We can observe some physical properties, such as density and color, without changing the physical state of the matter observed.
698098
Physical properties are used to observe and describe matter. Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others.

Laser radiation has the following important characteristics over ordinary light source. They are: i) monochromaticity, ii) directionality, iii) coherence and iv) brightness. (i) Monochromaticity: A laser beam is more or less in single wavelength. i.e., the line width of laser beams are extremely narrow.

Sound and light are similar in that both are forms of energy that travel in waves. They both have properties of wavelength, freqency and amplitude. Here are some differences: Sound can only travel through a medium (substance) while light can travel through empty space.

The terms light, electromagnetic waves, and radiation all refer to the same physical phenomenon: electromagnetic energy. This energy can be described by frequency, wavelength, or energy.

Physical properties include color, smell, freezing/melting point, and density.
