Types of light With Definition In physics

If you want to know about that Types of light With Definition  then you arrive at the right place let’s start with our main motive.

What is “light”?

Light is called a part of electromagnetic radiation which can be perceived by the human eye . In physics, light is known as the electromagnetic spectrum, which is why it includes light visible to the human eye as well as non-visible light . The branch that studies the behavior of light, its characteristics and manifestations is known as optics .

The human eye adapts to different lightings and considers them all as white, however the light has different shades, all light sources have different shades according to the frequencies of the different wavelengths . The same sets together create the illusion of a white light.

Light can be from infrared to ultraviolet. To determine the existing color gamut, a kelvin degree scale has been created that determines the color temperature. At a higher temperature the light is usually more bluish in color, while at a lower temperature there are more reddish rays.

light Defination and examples?

Light goes at a quick speed; truth be told, nothing voyages quicker than light. Its speed is around 300,000 km each second.


Some of the light energy examples are light from stars, fire, the sun, glowing coils, electric bulbs, flashlights, lasers, and light from kerosene lamps.

Light classification

The classification of the light can be done based on its quality:

  • Hard light : the rays of this type of light are relatively parallel , which is why a very high definition is created in the illuminated area, so there is a sharp transition between the shaded area and the illuminated area. This type of light allows to find imperfections in the relief of the skin, highlighting excessively the texture and the modeling of the surfaces. It can produce a hard and rigid high contrast and shadows that are unattractive to the eye and even false.
  • Soft light : these lights are the preferred when it comes to hiding imperfections and irregularities of different surfaces. It offers a uniform appearance without shadows , it is obtained with lights of wide coverage or by means of reflected light. To make the light have a soft appearance, some diffuser elements can be used infront of the focus or source from which the light comes, in this way the intensity of it is reduced. This type of light allows you to hide facial lines, wrinkles or age spots. Avoid highlighting and shaping and relief of figures, objects, face, etc. It contains a feature that is not known as convenient: it spreads everywhere, so it is not possible to cut it out. It can also create flat and flattened lighting and in this way can suppress the natural beauties of the reliefs and shapes.


What are the 5 types of light?

There are five kinds of light — and their corresponding kinds of shade — that tend to fit almost all the light conditions that we are likely to draw or paint: single-source light; double-source light; flat, diffused light; moonlight; and sculptural light.

What are the two general types of light?

There are two basic types of light sources: Incandescence and Luminescence.

What are sources of light?

A light source is anything that makes light. There are natural and artificial light sources. A few examples of natural light sources include the Sun, stars and candles. A few examples of artificial light sources include light bulbs, lamp posts and televisions.

How many types of light do we have?

There are four main types of lights, or light bulbs, currently available on the market: Incandescent. CFL, or compact fluorescent lamp. Halogen.

What are the parts of light?

The three components of light. Nature combines the soft, scattered light from the sky with the vibrant, focused light from the sun. In the home, this finds its parallel in ambient lighting which provides the basic brightness in a room, and zone lighting which focuses on selected areas.
