Geomagnetic waves are thought to be the lowest frequency (and, therefore, the longest wavelength) electromagnetic waves in the universe. They are generated by movements in planetary structures that modulate a planet's magnetic field to create the wave. Certainly lower frequency electromagnetic waves could be generated, but they would be artificial. A link is provided for some useful information.
The radio band is the least energetic section of the electromagnetic spectrum.
The last color you can see at the red end has the lowest frequency,longest wavelength, least energy per photon.The last color you can see at the violet end has the highest frequency,shortest wavelength, most energy per photon.
From least to greatest energy, the order would be: Infrared radiation < microwaves < blue light < orange light < X-rays This order is based on the electromagnetic spectrum, where the frequency and energy of radiation increase from left to right.
Yes. There are at least 90 billion trillion or more planets in the observable universe.
In my opinion, yes. There are at least 10 billion trillion Earth-like planets in the observable universe.

There are (at least) 4 : gravity, electromagnetic strong force, & weak force.
like the colors of the rainbow. violet has the least wavelength or the greatest frequency possible that humans can see and marks one end of the visible spectrum in the electromagnetic spectrum. red has the highest wavelength or least frequency possible that humans can see and marks the other end of the visible spectrum of the electromagnetic spectrum.

The electromagnetic spectrum is a continuum. The least energetic type of radiation may be found in what is known as "extremely low frequency" radiation (ELF). This is radiation with a frequency in the range 3-30 Hertz. ELF radiation can penetrate seawater and so is particularly useful for communicating with submarines.
The different types of electromagnetic waves are all basically the same phenomenon; they differ in the frequency, and hence (since they all travel at the same speed, at least in a vacuum), also in the wavelength.The energy per photon (the particles that correspond to the wave) is directly proportional to the frequency.
Electromagnetic radiation with the lowest frequency has the least energy. E = hv, where E is energy in Joules, his Planck's constant, 6.626 × 10-34 m2 kg/s, and v is frequency in Hertz.
Radio waves are the longest of the electromagnetic waves. Longer waves have less energy in them than shortwaves do. Some of the really short EM waves are so energetic that you can use them to cook food. (Microwave ovens).
Among the many categories of radiation in the electromagnetic spectrum, the radiation with the lowest frequency(longest wavelength) carries the least energy. This might be the audio-frequency radiation from speaker-wires,the 60-Hz radiation from utility power lines or AC line-cords within the home, etc.
Yes. At least, that's more or less one of the meanings of the word "dimension". Mind you, that doesn't mean that such parallel worlds actually exist (they may, or may not, exist); it just means that the word is used in this sense.
Answers to this question encompass a vast universe of possibilities. The game Scrabble has been around since at least 1948. Something new that did not exist then is the digital camera.
typically the carrier frequency has to be at least double the signal frequency but in order to get better results you want to choose a frequency that is at least 5 times the highest frequency you are designing for.
