What else can I help you with?
Why can you see bright lines from the hand held spectroscope when viewing a discharge tube of gas?
When viewing a discharge tube of gas through a hand-held spectroscope, bright lines appear because the gas inside the tube emits specific wavelengths of light when energized. The spectroscope separates the light into its component colors or wavelengths, allowing you to see the discrete emission lines characteristic of the gas present in the tube.
Substance that does not appear to be the same throughout?
A substance that does not appear to be the same throughout is called a heterogeneous substance. This means that its composition varies in different parts of the material, leading to visible differences in color, texture, or composition. Examples include a mixture of oil and water, or a salad with different ingredients.
What is the correct name for solid substance which appear whne some solutions are mixed?
A precipitate
What is the shininess or dullness of a substance called?
The shininess or dullness of a substance is called its luster. It refers to the way light is reflected off the surface of the material. Substances with high luster appear shiny, while those with low luster appear dull.
For a substance to appear black what must happen?
i think that it must reflect red light waves.
When light given off by a simple burning substance is viewed through a spectroscope it would appear what color?
A spectroscope is a device for producing and recording spectra for examination. When light given off by a simple burning substance is viewed through a spectroscope, a certain color will appear.
When light gives off by a burning substance is viewed through a spectroscope it would appear as?
a continuous spectrum with all colors blending together.
How does sunlight appear through a spectroscope?
When sunlight passes through a spectroscope, it is broken down into its individual wavelengths or colors, which appear as a spectrum of lines. Each line corresponds to a specific element or molecule present in the sunlight, allowing scientists to identify the chemical composition of the light source.

What color is smoke?
Smoke can be white, grey, brown, black, or other colors depending on what substance is burning.

Is there a substance that can make you appear dead for a short time?
no
What substance is likely to appear in urine whe the glomerulus is inflamed?
Protein is likely to appear in urine when the glomerulus is inflamed. Normally, protein is not filtered through the glomerulus; however, inflammation of the glomerulus can lead to increased permeability, allowing protein to pass through and be excreted in the urine.
What substance to appear white what must happen to all wavelengths of light?
must be reflected
How can a spectroscope be use to find out if a star is moving?
A spectroscope can determine if a star is moving by analyzing the light spectrum emitted by the star. When a star moves away from Earth, its light is redshifted, meaning the wavelengths are stretched and appear longer. Conversely, if the star is moving towards Earth, its light is blueshifted, with shorter wavelengths. By measuring these shifts in the spectral lines, astronomers can quantify the star's velocity relative to Earth.
What is a a syntheic substance that began to appear everyday life in the 1940s?
That could be nylon
Does caffeine naturally appear in foods?
Caffiene doesn't naturally appear in food, yet it does appear in plants as a natural substance and is a pesticide. The caffeine is then stripped off the plant and used in products such as coke or coffee.
