One of the most difficult subjects in most schools is physics, large percentage of the courses is not handled in this subject. one of the hardest things is the electromagnetic spectrum.
the electromagnetic spectrum is the energetic distribution of the set of electromagnetic waves, in other words is the electromagnetic radiation emitted or absorbed almost any substance.
the electromagnetic spectrum ranges from radio waves to gamma rays passing through many other levels, the levels of the electromagnetic spectrum are: radio, microwave, infrared, visible, ultraviolet, X-rays and Gamma rays. All these are reflected in the following image:
Electromagnetic spectrum, frequency of all levels:
Radiofrequency: ranging from extra low frequency (3-30 Hz) to extra high frequency (30-300 GHz).
Microwave: its frequency is between 1 GHz and 300 GHz.
Infrared: are in the range 0.7 to 100 microns.
Visible spectrum: its length is 0.4 to 0.8 microns, is perhaps one of the most important spectra. ranges from ultraviolet light to infrared light, as seen in the picture:
Ultraviolet: covers the range of 4 to 400 nm.
X-ray: is in the range in the range of 30 to 3000 PHz.
gamma rays: have the greatest amount of radiation and its frequency can not be measured.
X-ray: is in the range in the range of 30 to 3000 PHz.
gamma rays: have the greatest amount of radiation and its frequency can not be measured.
