Light is used for a number of purposes, the most basic being sight. When light hits something it deflects off of the object and when you look at the object the light that transfers into your eye creates the image before you. If there is little or no light, it becomes harder to see images and color.
Another use for light would be warmth. Sunlight, for example, warms the earth and keeps us from freezing. Without the sun we would be done. Excuse my pun. You notice how the temperature drops at night a few degrees? Well that's because we are blocked from the warm light that the sun emits.
Plants have other uses for light. They can literally take a sunbeam and turn it into food in a process called photosynthesis. In any case, Light has many uses.
What else can I help you with?
What are objects that emit light?
Objects that emit light are usually referred to as incandescent.
What are some examples of objects that emit or reflect infrared light?
Some examples of objects that emit or reflect infrared light include the sun, humans, animals, and electronic devices such as remote controls and infrared cameras.
How can objects which do not emit light be seen?
By definition, something which does not emit light cannotbe seen. However, it can be observed, in that its effects such as through gravity and electromagnetism can be detected.
Does every light source emit only one type of light, or can some light sources emit multiple types of light?
Some light sources can emit multiple types of light, such as white light sources that emit a combination of different colors.
What are some examples of objects that emit infrared waves?
Some examples of objects that emit infrared waves include humans, animals, hot objects like stoves or heaters, and electronic devices such as remote controls.

What objects in space produce their own light?
Objects in space that produce their own light are known as luminous objects. Some examples include stars, such as our Sun, which emit light through the process of nuclear fusion, and hot planets like Jupiter, which reflect and emit light due to their internal heat. Other examples include galaxies, supernovae, and nebulae that emit light due to various astronomical processes.
Name some stars that don't emit light?
Black holes and neutron stars are examples of stars that do not emit visible light. They can only be detected by their gravitational effects on nearby objects or through other forms of radiation such as X-rays or radio waves.
How does a radio telescope see objects which are too dim for an ordinary telescope?
Radio Telescope observe light of a different wavelength then optical light. Radio waves have a longer wavelength then visible light. Some interstellar objects barley emit any light in the visible spectrum but emit a significant amount of radiation in the radio spectrum. Radio telescopes enable us to view objects which emit in the radio spectrum.
Some things give out their own light these are said to be?
Some things that give out their own light are described as "luminous." This includes natural sources like the sun and fireflies, as well as artificial sources such as light bulbs and LEDs. Luminous objects emit light due to various physical processes, including incandescence, fluorescence, or bioluminescence. In contrast, objects that do not emit light but can reflect it are termed "illuminated."
Does every light source emit only one type of light, or can some light sources emit multiple types of light?
Some light sources can emit multiple types of light, such as white light sources that emit a combination of different colors.
What are the source of light for all objects in space?
The primary source of light for objects in space is usually stars, which emit light and other forms of electromagnetic radiation through nuclear fusion in their cores. Some objects in space can also reflect light from nearby stars or other sources, contributing to their overall brightness.
What are some examples of objects that emit infrared waves?
Some examples of objects that emit infrared waves include humans, animals, hot objects like stoves or heaters, and electronic devices such as remote controls.
Which of these objects reflect light and which emit light Comets Asteroids Planets Sun Meteors Stars?
Objects that reflect light include planets, asteroids, and comets. The Sun emits light as it is a star. Meteors are visible as they burn up in the Earth's atmosphere, reflecting some light. Stars emit their own light through fusion reactions.
What emits infrared light?
Objects that emit infrared light include hot objects and bodies that are giving off heat, such as the Sun, fires, and heated objects like stovetops. Additionally, some electronic devices like remote controls and night vision cameras emit infrared light as part of their functionality.
