Visible light goes "Roy G Bv": Red Orange Yellow Green Blue Violet• Blue light has higher frequency with shorter wavelengths , so has more energy than red
Gamma rays mostly pass through, but any that get absorbed may harm our cells by ionization see below So some waves pass right through our bodies, others get reflected or absorbed at different rates As Photons Electromagnetic radiation behaves as waves, but also behaves as packets of energy called Photons

الطيف الكهرومغناطيسي

So telescopes like the NuSTAR X-ray telescope have to be in orbit.

ما هو الإشعاع الكهرومغناطيسي؟
طيف كهرومغناطيسي
It goes: Radio, Micro, Infrared, Light, Ultraviolet, Rays• The spectrum is continuous with no sudden changes or boundaries

Einstein wrote about it: "It seems as though we must use sometimes the one theory and sometimes the other, while at times we may use either
This is called the "wave—particle duality"
Example: Which has more energy, red light or blue light? have low frequencies, low energy and long wavelengths• Ranges We like to think of the spectrum as having these ranges:• But how waves interact with matter depends on their energy and the type of matter Example: Our Bodies• This effect heads off through space at the fastest speed possible: the speed of light

الطيف الكهرومغناطيسي وأسراره الفيزيائية

Speed of Light Electromagnetic waves travel at the "Speed of Light" at almost 300,000,000 meters per second to be exact: 299,792,458 meters per second in a vacuum.

So electricity and magnetism are linked in an ongoing dance
تعريف الطيف الكهرومغناطيسي
186,000 miles per second But the speed can be slower
ما هو الإشعاع الكهرومغناطيسي؟
This makes atoms charged and more likely to form new chemical reactions, which can be harmful to our cells, killing them or changing them so they grow out of control and form cancer
