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.
Yes a candle is a light source. Actually, the unit for intensity of light (candela) is based on the light emitted by a candle.
A polilght is a portable,high-intensity, fitered light source used by forensic scientist
Spectral class is classification of stars by their external features..Like light,temperature etc..
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.
Alpha Centauri A - It is 4.365 light years away and has a spectral class of G2V the same as our Sun

A photoelectric to convert light intensity into a resistance.
Light intensity is inversely proportional to the square of the distance: I = k/d2
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.

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.
The intensity decreases.
As light gets farther from the source, the same amount of light spreads out over a larger area.
what is spectral evidence Spectrum (spectral) refers to different frequencies of light associated with a substance.

Switching to a brighter light source. Switch to a light source with a higher intensity.
