The electromagnetic waves that have the highest energy PER PHOTON are called gamma rays.
Penetrating what?
For sea water the answer is very low frequency.
For air (or glass) its the visible spectrum.
For fog its infra-red.
The visible spectrum (the radiation we can see as light). This is most likely why organisms evolved to be able to see visible light over other types of electromagnetic radiation - the sun emits this more than the other frequencies, so it was easier for life to evolve seeing this spectrum.
Hydrogen nuclei undergo fusion within the Sun and this reaction releases energy as 0.3% of the hydrogen's mass is converted into energy. This energy spans several bands of the electromagnetic spectrum, most of it is in the UV-Vis portion. For more information look up blackbody radiation.
Ultraviolet. Most of the spectrum is invisible to people.
Quite simply, the Microwave Oven uses the Microwave part of the spectrum.
Every part of the electro-magnetic spectrum could be used for communications however the most exploited are long radio waves, short radio wave, and micro-waves.
The waves with higher frequencies have more energy and the gamma rays have the most energy in the electromagnetic spectrum
Gamma Rays
The ones with the highest frequency.
the electromagnetic waves with high frequency carries most energy ex :gamma rays
Most of the electromagnetic spectrum is not visible.
Most of the electromagnetic spectrum is not visible.
Red, I believe.
The visible spectrum is a tiny, almost negligible slice of the electromagnetic spectrum. 'Sonar' has no place in this discussion. It's not even electromagnetic.
Most of the electromagnetic spectrum is not visible.
All parts of the electromagnetic spectrum cause heat, and fires emit EM radiation based on a plank curve. However, in the majority of "normal" fires, the most common source is in the infrared spectrum.

Most waves from the em spectrum reflect off the atmosphere and the ozone layers Hope this helped
