In order to fully understand continuous spectrum chemistry it is important to discern electromagnetic spectrum white light is a continuous spectrum but this is only part of a larger electromagnetic spectrum that contains radio waves infrared rays microwaves ultraviolet gamma rays and x rays.
Light source continuous spectrum.
When an absorption spectrum and emission spectrum are combined you get a continuous spectrum with all the wavelengths.
Spectrum of light emitted by a deuterium lamp showing a discrete part tall sharp peaks and a continuous part smoothly varying between the peaks.
Truly white light like that emitted by some stars and moons is a perfect example of continuous spectrum.
Stars and stellar spectra.
Full spectrum products are usually marketed as electric light sources that emulate.
What are full spectrum light sources.
Broadband light sources then overlap and form a continuous i e nondiscrete spectrum.
The sun s light is also believed to produce continuous spectrum since we can see the rainbow.
The term full spectrum is not a technical term but rather a marketing term implying a smooth and continuous spectral power distribution spd without the spikes and troughs in radiant energy common with most discharge light sources e g fluorescent and metal halide.
Similar phenomena occur in high pressure arc lamps in which broadening of spectral lines occurs owing to high collision rates.
