1. Energy Carried by Electromagnetic Waves

2. The Energy of a Photon
The amount of energy carried by a photon depends on its frequency or wavelength.
The higher the frequency (or the shorter the wave) the proportionately more the energy it carries.

3. This means that higher frequency EM waves come from more energetic - or hotter - sources.
Gamma ray bursts lasting more than two seconds are caused by massive exploding stars at the end of their lives.

4. Because higher frequency waves carry more energy and are small enough to enter cells, they can be more harmful to life, causing mutations, cancer, or even death.

5. Transparency
What an EM wave can pass through depends on its frequency. For example,
FM radio waves CAN pass through solid objects, while AM radio waves CANNOT.

6. Our atmosphere and magnetosphere allows some waves through but not others.
Harmful Gamma Rays, X-Rays, and some UV light waves are blocked.

7. For example, Earth’s magnetosphere protects it from the Solar Wind, which contains high frequency EM waves.

8. Telescopes on earth are limited as to what they can “see,” due to our atmosphere’s blocking of most EM waves, and its actual gas molecules deflecting or “scattering” the light.

9. Space telescopes beyond our atmosphere are able to view objects emitting non-optical light, as well as optical lit objects, without distortion.
