What else can I help you with?
AM radio signals are?
Amplitute Modulation signals. a modulation(mixing)method used in early radio transmissions.in many countries, radio transmissions below 30 Mhz,are still using this method.short wave,medium wave transmissions,and some extent of VHF transmissions are possible in this method.
What are Gamma Ray bursts and what is their amplitude and when do they occur?
A gamma ray burst is a beam of extremely high energy electromagnetic radiation (light) with a wavelength below 10^-11 m, or less than .01 nm (nanometer), emitted by the collapse of a massive star, with a mass around 1000 times that of our sun. These beams usually last between 5-40 seconds. When they occur, they have more energy than the rest of the universe combined. Most gamma ray bursts occur when a massive star (white dwarf, neutron star, red or blue super/hyper giant) collapses into a black hole. When the star runs out of fusible fuel, when the fusion cycle first produces iron. The outer layers of the star fall under the force of gravity onto the inner core. When they impact, this sets out massive compression shock waves both into the core, and out though the outer layers. In the outer layers, the shock wave triggers massive runaway fusion reactions which blast the star to pieces, a supernova. In the inner core, the shock waves compress the core matter to unimaginable densities; to the point where the stellar core the mass of our entire sun is compressed to a volume less than a cubic mile. The force of its gravity warps space-time, creating a black hole. The new back hole immediately begins sucking up the stars outer layers. But, because there is so much matter, it can't be sucked up faster enough. Atoms are packed extremely close together, moving chaotically, and tempuratures exceed 1,000,000 degrees. The produces unimaginable amounts of energy; this energy is shot out of the star at it's north and south poles, as a gamma ray burst. To my knowledge no one has ever measured the amplitude of a GRB. The absolute magnitude is in excess of -30, a few hundred times brighter than our sun.
