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.
What system of the body protects us from harmful substances and removes wastes from cells?
The immune system protects our body from harmful substances by identifying and combating pathogens such as viruses and bacteria. The excretory system removes wastes from cells through organs like the kidneys and liver, filtering out toxins and maintaining the body's internal balance.
Through which organelle do substances enter or leave a cell?
Substances pass through the plasma membrane, although ot is not technically an organelle.
When substances go through chemical changes?
After chemical reactions new substances are obtained.
What are the two substances transported through phloem tissue?
The two main substances transported through phloem tissue are sugars (such as sucrose) and amino acids. These substances are transported from the leaves, where they are produced through photosynthesis or other metabolic processes, to other parts of the plant for growth and metabolism.
What is the purpose of using spectroscope?
to evaluate the effects on a beam of light when it is passed through certain substances.
Do you look through a spectroscope with your eyes?
yes you do i think
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.
Why do astronomers look at stars through a spectroscope?
To learn what they are made of.
What wavelengths of light are indicated by the following scale readings observed through a hand spectroscope?
To determine the wavelengths of light indicated by scale readings observed through a hand spectroscope, refer to the calibration markings on the spectroscope. Each marking corresponds to a specific wavelength of light. By aligning the observed scale reading with the markings on the spectroscope, you can identify the wavelength of the light being observed.
A spectroscope relies on?
A spectroscope relies on the phenomenon of diffraction. This scientific instrument separates light into its different wavelengths. It was invented in 1814 by a German optician, Joseph von Fraunhofer.
What is an atmolyzer?
An atmolyzer is an instrument used for carrying out atmolysis, the separation of mingled gases of unequal diffusibility by transmission through porous substances.
What is viewed through a spectroscope?
Either "a spectrum" or "a light source" (usually), depending on exactly what you mean. The "usually" is because there are some kinds of instruments called spectroscopes that use a different principle. One example would be a "mass spectroscope".
A spectroscope is designed to separate what into component colors?
A spectroscope is designed to separate light into its component colors. This is achieved by passing light through a prism or diffraction grating, which disperses the different wavelengths of light, creating a spectrum of colors that can be analyzed.
Why is a spectroscope illuminated?
A spectroscope is illuminated to provide a light source that can be broken down into its individual wavelengths when passed through a prism or grating. This allows scientists to analyze the different wavelengths present in the light source, which can provide information about the composition and properties of the source.
What does every element emit if it is heated by passing an electric discharge through its gas or vapor?
Every element emits a unique spectrum of colored lines when heated by passing an electric discharge through its gas or vapor. This is known as the element's atomic emission spectrum, and can be used to identify the element.
Is clarinet a wind instrument?
Yes, any instrument that you blow through is a wind instrument.
