The gravitational force exerted on the satellite is called the centrifugal force, the force keeping it orbiting to the planet. Its formula is F= mass times the square of the velocity all over the radius.Thus,
Scientists call them all electromagnetic radiation. The waves of energy are called electromagnetic (EM) because they have oscillating electric and magnetic fields. Scientists classify them by their frequency or wavelength, going from high to low frequency (short to long wavelength).
<h2>Answer: As the star spins, beams of radio radiation from it sweep through space. If one of these beams points toward the Earth, we observe a pulse.</h2>
A pulsar (<u>pul</u>sating <u>star</u>) is a neutron star that emits very intense jets of electromagnetic radiation in the range of radio waves, X-rays or gamma rays, at short and periodic intervals due to its intense magnetic field that induces this emission.
This jet is <em>"observable"</em> on Earth, when the magnetic pole of the star <em>"points"</em> to our planet and then stops pointing a thousandth of a second later due to the fast rotation of the star, appearing again when the same pole returns to point towards Earth.
Then, what is observed in the terrestrial sky are pulses of radiation with a very exact period, which are repeated again and again.
