White dwarfs are dim because they are small, and small stars radiate less light.
heat and light.
Yes. All naturally occurring elements in the universe can be found in most stars, though generally only in small concentrations. Massive stars that have depleted the hydrogen in their cores may start producing elements as heavy as iron.
Dwarf stars are small and give of very little light. Which is what makes them so hard to find.
No. However, the stars do use a different form of nuclear energy, called nuclear fusion or fusion.In fission, heavy elements such as uranium are broken down into smaller elements, releasing huge amounts of energy in the process. This is used in power plants on Earth and was used in the first nuclear bomb dropped on Hiroshima, Japan.In fusion, however, light elements starting with Hydrogen, the most abundant element in the Universe, are actually fused together into heavier elements such as Helium. Stars use this because there is SO much Hydrogen in the universe, and stars are full of it. Fusion requires a tremendous amount of energy to kick-start, but in return an even more tremendous amount of energy is released. That is what powers the stars. Currently, it is believed that elements up to oxygen (8) exist in our Sun.
Light elements combined to form the heavier elements.
Elements are the same size regardless of how they are synthesized. It is true, however, that small stars create fewer elements, and that the elements they create are lighter. A normal G-type star can, during the course of its evolution along the Main Sequence, produce elements up to iron. For elements heavier than that, larger stars are required; when they go nova, they can produce elements as heavy as uranium and beyond.
The elements on the visible part of distant stars can be obtained from the star spectra, that is, by analyzing the light that comes from the stars.

Light elements are made in light weight stars via stellar nucleosynthesis. Elements as heavy as iron form in the cores of massive stars. Anything heavier than iron requires a supernova--the collapse and explosion of a super massive star.
stars turn hydrogen into heavier elements in nuclear fusion. this process gives off light and heat.
Light from the stars is energy. However, the amount of energy that this light accounts for is too small to be of any use.
Stars give out light. The sun is a relatively small star but it's a a lot close than the others making it appear bigger. Stars are explosions and give out light.
White dwarfs are dim because they are small, and small stars radiate less light.
every star has different elements in the atmosphere which absorbs the light
It is helpful to study the light that comes off stars because the light from a star gives hints of what elements make up a star. This is due to the fact that the light is a wave.
