Becuase they are hot!
A luminous ball of plasma is a hot, ionized gas that emits light and energy. Examples include stars like the Sun, which are giant luminous balls of plasma that produce light through nuclear fusion in their cores. Plasma balls can be observed in phenomena such as lightning, neon signs, and some types of artificial lighting.
Microwave plasma balls are created by applying microwave energy to a gas, which ionizes the gas and creates a plasma ball. These plasma balls have unique properties such as high temperatures, high energy densities, and the ability to generate intense light and heat. They are used in various applications such as material processing, surface treatment, and plasma chemistry.
plasma is electricity and light but light is not a plasma
no
That's called a star. Actually stars are balls of plasma - where plasma can be thought of as a special case of a gas.
Blood Plasma is one of the many things that make up what humans use as blood. Plasma is usually a light yellow or straw colour
Anything that excites the gas in a fluorescent will make it light. Static electricity from the carpet will cause compact fluorescent to light.
The plasma make when the plasma ready.
Plasma
Plasma is a substance that can be both liquid and gas at the same time. It is formed when an air or gas is ionized and releases free electrons. Specific examples of plasma are balls of lightning, fluorescent light bulbs, and the Northern Lights.
In plasma, optical thickness refers to the measure of how effectively the plasma interacts with electromagnetic radiation, such as light. It accounts for the absorption and scattering of light as it passes through the plasma. A higher optical thickness indicates a greater interaction between the plasma and light.
When light passes through a plasma, it can interact with the free electrons and ions within the plasma, causing scattering, absorption, and emission of light at different wavelengths. This interaction can result in phenomena such as refraction, diffraction, and interference, altering the properties of the light as it passes through the plasma.
