The intensity of a line is proportional to the number of photons emitted or absorbed by the atoms. It depends on the number of atoms giving rise to the line.
Spontaneous emission occurs randomly and naturally when an excited atom transitions to a lower energy state, releasing a photon in the process. Stimulated emission, on the other hand, is induced by the presence of external photons that cause an already excited atom to release a second identical photon. In spontaneous emission, the emitted photon may have any frequency within the spectral line width of the transition. In stimulated emission, the emitted photon has the same frequency, phase, direction, and polarization as the stimulating photon. Spontaneous emission is non-coherent and occurs independently of external radiation. In contrast, stimulated emission is a coherent process that contributes to the amplification of light in lasers. The rate of spontaneous emission is independent of the intensity of external radiation, while the rate of stimulated emission is directly proportional to the intensity of the stimulating radiation. Spontaneous emission plays a role in processes like fluorescence and phosphorescence, whereas stimulated emission is the principle behind the operation of lasers.
a Edit: The question is very mixed up, but I think I get the idea. It's obviously an emission spectrum. Because it is a high density gas the spectrum should be CONTINUOUS.
ICP-AES (Inductively Coupled Plasma-Atomic Emission Spectroscopy) measures the intensity of emitted light from excited atoms to determine elemental composition, while ICP-OES (Inductively Coupled Plasma-Optical Emission Spectroscopy) measures the intensity of emitted light and analyses the wavelengths to determine elemental composition. ICP-OES typically provides higher sensitivity and lower detection limits compared to ICP-AES.
Decibels measure the intensity of sound, not the frequency. The perceived loudness of a sound at 500 Hz would depend on factors like the amplitude or intensity of the sound.
Low light intensity lowers the rate of photosynthesis, Normal sunlight is good for a normal rate of photosynthesis, Very high intensity bleaches (destruction) the chlorophyll
Niels Bohr studied the emission lines of Hydrogen.
Emission refers to the release of radiation from a source. This can occur in various forms such as light, heat, or particles. Emission can either increase the intensity of radiation or change its properties, depending on the source and energy involved.

One experiment could involve varying the material of the absorbing/emitting surface while keeping all other factors constant, to determine the effect of material type on absorption and emission. Another experiment could involve changing the temperature of the surface and observing how it affects the absorption and emission spectra. Additionally, one could vary the intensity or wavelength of the incoming radiation and measure the corresponding absorption and emission characteristics to study their dependence on these factors.
The number of lines in the emission spectrum is the same as in the absorption spectrum for a given element. The difference lies in the intensity of these lines; in emission, they represent light being emitted, while in absorption, they represent light being absorbed.
The intensity of sound is dependent on the amplitude of the sound wave. The higher the amplitude, the greater the intensity of the sound. It is measured in decibels (dB) and corresponds to the loudness of the sound.
Mass of object and distance from it
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.
Its volume or how loud it is.
The answer will depend on the addiction - both the substance (or activity) and intensity.
* emisssion of electron from the surface of the metal when light of suitable frequency falls-photoelectric emission. * emision of electron from the metal by quantum tunnling of electron.
