Electromagnetic Spectrum Lab Report
grin007 [14]

Answer:

The purpose or objective of the electromagnetic spectrum experiment the purpose is to figure out what elements are in the planets’ and the moons’ atmospheres by looking at their absorption spectrums

Explanation:

What is electromagnetic spectrum?

The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies.

The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10^25 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are called by different names; beginning at the low frequency (long wavelength) end of the spectrum these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays at the high frequency (short wavelength) end.

The electromagnetic waves in each of these bands have different characteristics, such as how they are produced, how they interact with matter, and their practical applications.

The limit for long wavelengths is the size of the universe itself.

Don't know if this helps or not :)
