Do atoms give off radiation that determines the colour?

In summary, the conversation discusses the concept of how objects get their color and suggests doing a Google search to learn more about it. It also mentions that not all colors of light are scattered equally and some objects can emit their own light. The speaker advises the listener to do more reading and properly label the thread before asking more specific questions.

There is quite a bit written about hoe objects get their colour - have you tried a google search?
This sort of question is commonly posed as a homework research assignment - but even if this is not the case, it is a good exercize for you to try finding out for yourself: you will learn more that way.

Generally - you see objects because light from the Sun (or other light source) gets scattered off the surface and some of that light ends up in your eyes.
Not all colours of light are scattered equally, and some colours get absorbed, so they don't scatter at all.
Not all colours are available in the light all the time either ... but when they are, it is called "white light".
... and some objects to emit their own light.

With that in mind - have another look through the internet and tell me what you find.

@LSMOG, please do some reading first and come back if you have more precise questions. Also, be careful to properly label the thread: you had indicated an Advanced thread, but this is definitely Basic.

Thread closed.
 

1. What is radiation and how is it related to color?

Radiation is the emission of energy in the form of waves or particles. The color of an object is determined by the wavelengths of light that it reflects, absorbs, or emits. This means that the type and amount of radiation given off by atoms can affect the color of an object.

2. Do all atoms give off radiation?

Yes, all atoms give off radiation in the form of electromagnetic waves. This radiation can range from radio waves to gamma rays, depending on the type of atom and its energy level. However, the amount and type of radiation given off by atoms can vary greatly.

3. How does radiation from atoms determine the color of objects?

Atoms contain electrons in different energy levels, and when these electrons move between levels, they release energy in the form of radiation. This energy can be absorbed or reflected by nearby objects, which can then be perceived as color. For example, the green color of plants is due to the absorption of red and blue light by chlorophyll molecules, which are made up of atoms.

4. Can radiation from atoms be harmful?

Yes, certain types of radiation given off by atoms can be harmful to living organisms. This includes ultraviolet radiation from the sun, which can cause skin damage and increase the risk of skin cancer. Additionally, exposure to high levels of radiation can lead to serious health effects, such as cell damage and radiation sickness.

5. How do scientists study the radiation given off by atoms?

Scientists use a variety of techniques to study the radiation given off by atoms. This includes spectroscopy, which involves analyzing the unique wavelengths of light emitted or absorbed by atoms, and particle accelerators, which can accelerate atoms to high energies and study the particles they emit. Additionally, scientists can use specialized instruments to detect and measure radiation, such as Geiger counters and radiation dosimeters.
