How does the intensity of a spectral line yield information about the source of the light?

Intensity of spectral line show the abundance of different elements in the light source. Every element has its own "fingerprint" which can indicate its presence.

Is a candle a light source?
Yes a candle is a light source. Actually, the unit for intensity of light (candela) is based on the light emitted by a candle.
What is the polilight?
A polilght is a portable,high-intensity, fitered light source used by forensic scientist
What is spectral class?
Spectral class is classification of stars by their external features..Like light,temperature etc..
Astronomers can learn about bodies in space by studying the patterns formed from?
the light rays that are 'bent'[refracted] as they pass through a prism, and then focused upon the receiving 'tray' that contains the film that is processed to form Spectrographs. Spectrographs are of two types: emission - spectral lines that result from the emission of photons at absolutely specific spectral lines [wavelengths], and - absorption spectral lines that are missing due to the absorbent nature of the interstellar gas & matter clouds that the Source Light passes through.
What nearby star is in the same spectral class as the sun?
Alpha Centauri A - It is 4.365 light years away and has a spectral class of G2V the same as our Sun
How does the intensity of the spectral line yield information about the source of the line?
Intensity of spectral line show the abundance of different elements in the light source. Every element has its own "fingerprint" which can indicate its presence.
What is the detector in a spectrograph in which spectral lines are recorded photographically?
A photoelectric to convert light intensity into a resistance.
How does light intensity vary with distance form the source?
Light intensity is inversely proportional to the square of the distance: I = k/d2
Is the brightness of glow in the dark materials affected by the light source used to make them glow or only by the intensity of the light Does the light source?
It depends on the luminescence of the materials. I see no difference between "the light source" and "the intensity of the light". Please restate and/or clarify the question.
Is a candle a light source?
Yes a candle is a light source. Actually, the unit for intensity of light (candela) is based on the light emitted by a candle.
Why do things have colour?
Color only exists because of spectral light, and the ability of our eyes and brains to process the sight light inro a definitive color. The color of an object depends on the color or intensity of the light bouncing off of it.
What happens to the illuminance when you move away from the light source?
The intensity decreases.
Why does the intensity of light change with distance?
As light gets farther from the source, the same amount of light spreads out over a larger area.
What is''spectral evidence?
what is spectral evidence Spectrum (spectral) refers to different frequencies of light associated with a substance.

If you are running a photoelectric effect experiment which adjustment might cause more current to flow?
Switching to a brighter light source. Switch to a light source with a higher intensity.
What is the polilight?
A polilght is a portable,high-intensity, fitered light source used by forensic scientist
