What is the source of heat and light for all the plants?
The sun is the source of heat and light for plant-life.
A red light source and a green light source shine on a white screen what color will the screen be?
If the screen is actually white, it will absorb all light and appear black to your eye. If the screen appears white in normal light, all light will be reflected resulting in the combination of green and red (brown/yellow).
Does light waves travel fastest through empty space?
Light waves, like all electromagnetic waves, travel without a medium, so they can travel through empty space. Sound waves, on the other hand, do require a medium to travel or propagate; therefore, they can not travel through empty space.
How are light rays coming from a point source of light different then larger source?
From a point source, the light spreads out in all directions and adjacent light waves diverge from one another. From a larger source, it appears more like the light waves are moving parallel to each other, with little divergence. It's a relative thing. From the perspective of Earth, the Sun's rays are all parallel to each other because the Sun is huge and also because we are so far away from it. So the key differences are: 1. Small, point like source. 2. Being close to the source. Combinations of 1 and 2 above produce more divergent rays. Either of 1 and 2 below (or a combination of the two) will produce more parallel rays that don't diverge much. 1. Large light source 2. You're far away from the source.
Is White light is made up of an mixture of many colors of light?
White light is what we see when light of all (or most) of the frequencies in the visible spectrum are emitted together from the same source. It is the combination of every visible light wave.
What is the source of all light in outer space?
The source of light in outer space varies. Light can be reflected off from the stars, moons, comets, asteroids and planets.
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.
Why is sun a natural source of light?
The Sun is a natural source of light because it emits electromagnetic radiation, including visible light, through the process of nuclear fusion in its core. This light travels through space and reaches Earth, providing us with the light and energy we need for life to thrive.
Photons travel outward from a light source in?
the photons travel outward from a light source in all directions.
What is the source of heat and light for all the plants?
The sun is the source of heat and light for plant-life.
What is the difference between light source and an illuminant?
The terms light source and illuminant have precise and different meanings. A light source is a physical emitter of radiation such as a candle, a tungsten bulb, and natural daylight. An illuminant is the specification for a potential light source. All light sources can be specified as an illuminant, but not all illuminants can be physically realized as a light source.
How does a space probe live?
it gains all its energy from the sun or some source of light to survive on and for landing on a planet it uses air bags stuffed in it
Can light travel through space?
Light can travel through space. All the light that we get on the earth's surface; usually travels from the sun through space before it can reach here.
Is a television a light source?
Yes, as long as the TV is on and in working condition.
