The idea that light consisted of streamers emitted by the eye was proposed by the ancient Greek philosopher Empedocles. He suggested that vision occurred when these emitted rays interacted with objects, allowing sight. This notion was later challenged and replaced by more accurate theories of light, particularly with the work of scientists like Isaac newton and Christiaan Huygens.
What else can I help you with?
How did sir isaac newton influenced the way people thought about light?
he said that light consisted of different wavelengths and when it is passed through a prism the wave lengths get split up and form different colours
Do stars have electromagnetic waves and how is it a known fact of this information?
Stars don't have electromagnetic waves. They absorb them and release them. It is not a known fact because electromagnetism is only a theory for now. However, light that reach us from stars are said to be EM waves because visible light is theorized to be in the EM spectrum.
Why the color black is said to be able to absorb the most light and produce the most heat?

What do you mean by biaxial crystal?
Certain substances will split a ray of light into two slightly different paths by polarisation. If a crystal transmits light without splitting it in this way when the light is incident on the crystal in only one direction then the crystal is said to be uniaxial. If light is transmitted when it is incident in either of two directions then the crystal is said to be biaxial. Please see the links.
What are photoblastic cells?
Seeds that are stimulated to germinate by light are described as positively photoblastic; seeds whose germination is inhibited by light are said to be negatively photoblastic . The response to light is apparently mediated by a phytochrome. The word itself means: photo=light + -blast= build.
How do astronomers observing distant galaxies talk about looking backward in time?
The speed of light is not infinite. Light takes time to travel from distant galaxies to our eyes here on Earth. If a galaxy is 1 billion light years away, it has taken 1 billion years for the light emitted by said galaxy to reach us here, so (obviously) we are seeing the light emitted 1 billion years ago. In a sense, we are seeing 1 billion years into the past at the light emitted by that galaxy.

What are coherence?
COHERENT WAVESWhen the light waves are emitted from a single source and they have the zero phase difference between them then the waves are said to be coherent. The coherent waves are shown below:
How does amplitude affect color?
Amplitude does not directly affect color. Color is determined by the wavelength of light that is being reflected or emitted. Amplitude relates to the intensity or brightness of the light.
What are objects that reflect scatter or transmit light said to be?
Objects that reflect light are said to be "reflective", objects that scatter light are said to be "diffusive", and objects that transmit light are said to be "transparent" or "translucent".
Who said let there be light?
Supposedly God said "Let there be light"
What happens when the electrons return from the excited state to the ground state?
When electrons return from an excited state to the ground state, they release energy in the form of photons. This process is called emission and is responsible for the production of light in some cases, such as in fluorescent light bulbs or lasers.
Why do some materials glow in ultraviolet - UV - light?
UV light is invisible to the human eye, which is why it is sometimes referred to as 'black light'. However, some materials (e.g. DayGlo) can absorb UV energy and convert it into visible light energy. They are said to be fluorescent.
Where does light live?
She lives in Los Angeles She and husband Freddy divorced and she left Bodyrock.tv and now has her own fitness YouTube channel.
Where in the Bible does it say and then there was?
" He said let there be light, and then there was light"
What is a lh4030s3l light cart?
As you said its a light cart.
Who said that light can be pulled by the gravity?
Albert Einstein said that.
