Yes it does. It contains all the forms of radiation, but 99% of its energy is carried by radiation with wavelengths between 278 and 4600 nm, with the maximum at 4720 nm.
what does an electromagnetic spectrum consist of
Because it doesn't absorb any wavelengths in the visual region of the electromagnetic spectrum. This is actually characteristic of alkaline earth metal salts, at least those where the anion does not contain a transition metal.
A fluorescent lamp contain mercury so the identities of spectrum are normal.
If there were colors, that part of the spectrum would not be invisible.
When an observer points his radio telescope onto an area in the skies which is supposed to contain a black hole, received signal will be carrying information mostly about X-rays (part of spectrum beyond visible violet color) which are emitted when that black hole consumes matter.
what does an electromagnetic spectrum consist of
Yes. Precisely.
p
No.
b/c they contain chlorophyll which has green pigment
visible light
Electromagnetic radiation from the sun covers the entire spectrum including what we commonly call sunlight and X-rays. We often refer to the term sunlight to mean light in the visible spectrum, though it can be thought of as including infrared and ultraviolet light. Does sunlight contain X-rays? That depends on how you define sunlight.
Light contains energy in the form of the photons of electromagnetic radiation
Remember that all light is electromagnetic radiation, which includes everything in the electromagnetic spectrum from long wave radio waves to gamma waves. These waves impart their energy to charged particles via the photon, which is the carrier particle for the electromagnetic force. Ultraviolet radiation, unlike longer wavelength radiation, contains enough energy to promote electrons from lower orbitals to higher orbitals, which may cause a variety of "dangerous" results. For example, when your skin absorbs UV radiation, electrons in the atoms of your skin cells, or worse, in your DNA, are promoted and cause the molecules which contain them to become unstable. Even worse, short wavelength UV radiation may cause ionization, which results in a charged, and thus reactive, molecule. Unregulated reactivity in the body can result in diseases like cancer.

it contains an anode and cathode of the metal to be Analise,other than this it having the sample to be analysed in a vapour state to absorp energy from catode to go higher energy state.
The electromagnetic spectrum is a continuum so that the boundaries between its parts are arbitrary.From waves with the largest wavelengths (lowest frequencies and energies), they are:sub-radio frequencyradio wavesmicro-wavesterahertz radiationinfra redvisible lightultra violetx-raysgamma raysThe arbitrariness is seen in the boundary between visible and ultraviolet, for example. Many insects can see near ultraviolet.
