[3] Other sources restrict the use of the word to temporary, reversible vision loss: "...These are, in order of increasing brightness: dazzle, after image formation, flash blindness, and irreversible damage. The explosion's mushroom cloud stretched 40 kilometers into the sky, dispersing nuclear fallout across thousands of square kilometers in the Pacific. But if the duration of the power producing explosion is 1 millionth of an hour, the power would be 17x10^15 watts. Will Trump simply fffffffffaaaaaaaaddddddddeeeee away? An illustration of one of the brightest and most energetic supernova explosions ever recorded. Cosmic background radiation allows us to measure the radiodioactive waves of the sun. So if a tape measure is old it doesnt reflect changes in measurements? Save. At some sporting events such as figure skating, fans are cautioned to not use flash photography so as to avoid distracting or disorienting the athletes. It is unclear whether pain is directly associated with flash blindness. This causes these components to emit low-energy (“soft”) x-rays and high-energy (“hard”) ultraviolet waves. Also in aviation, there is concern about laser pointers and bright searchlights causing temporary flash blindness and other vision-distracting effects to pilots who are in critical phases of flight such as approach and landing.

Effects of a Nuclear Explosion Damage caused by nuclear explosions can vary greatly, depending on the weapon’s yield (measured in kilotons or megatons), the type of nuclear fuel used, the design of the device, whether it’s exploded in the air or at earth’s surface, the geography surrounding the target, whether it’s winter or summer, hazy or clear, night or day, windy or calm. Save. A 1-megaton explosion can cause flash blindness at distances as great as 13 miles on a clear day, or 53 miles on a clear night. The corresponding explosion produced a bright flash and a powerful electromagnetic pulse (EMP). so how many solar lmonisties is it? An H-bomb? There's only proof of cosmic background radiation and equations to help me back up my claim, Point source of illumination equation: E=P/4pie(radius)^2, If an object is illuminated by a point source of light, then the illuminate at the object to the luminous flux of the light source, divided by the surface area of the sphere, whose radius is equal to the distance the object is from the light source. It consists of weapon debris, fission products, and, in the case of a ground burst, radiated soil. Take a class in physics and you will realize what an ignorant answer you posted for idiots to base their research on. I think there were armaments there,” Coppe told the publication. Join Yahoo Answers and get 100 points today. Flash blindness, in contrast, is caused by a single, very brief exposure which oversaturates the retina, and is not usually accompanied by reports of pain. Flash blindness is caused by bleaching (oversaturation) of the retinal pigment. The Castle Bravo hydrogen bomb detonated that day had an explosive yield of 15 megatons, making it the most powerful nuclear device ever detonated by the United States. Assuming no friction and neglecting air resistance, -? Download this Free Vector about Bright nuclear explosion web banner, and discover more than 10 Million Professional Graphic Resources on Freepik Depending on the source consulted, term may exclusively refer to a temporary condition or may describe a potentially permanent one. If the fission explosion is an airburst, the residual radiation will come mainly from the weapon debris. [6] "A 1-megaton explosion can cause flash blindness at distances as great as 13 miles (21 km) on a clear day, or 53 miles (85 km) on a clear night. Actually, no, no I don't know what you mean. For example, the subject of a flash photograph can be temporarily flash blinded. Flat bright nuclear explosion effect. ...

Gunpowder has been used in warfare longer than the 16th century, but it was in the 16th and early 17thcentury that gunpowder really took off as the main way armies fought each other. Still have questions? There isn't any "too be honest" in science. The initial explosion creates a nuclear flash. As the nuclear explosion begins, the bomb and all of its components are heated to extremely high temperatures of around ten million kelvin. Wincing from temporary blindness, you'd scan the horizon and see an orange fireball. Nuclear explosions can cause significant damage and casualties from blast, heat, and radiation but you can keep your family safe by knowing what to do and being prepared if it occurs. During a nuclear explosion, dirt, debris and other particles are forced upward into the atmosphere in a giant cloud. “You can clearly see a brick orange column tending to bright red, typical of lithium participation. Flat nuclear bomb in a city. If you live in the southern hemisphere, you now can safely view the aftermath of a nuclear explosion from the comfort of your own backyard. The time between fission generations is only about 10 nanoseconds, so we can estimate that a nuclear chain reaction in an atom bomb takes around a microsecond from start to finish. Save. During the Cold War, the US government launched a 1.4 megaton bomb into space. Are the chances of rolling a 12 the same as 7 in a 6 sided die? Like. If we assume acceleration is negative downwards, so -9.8 m/s, would we have to make distance negative as well in the equation? What is its gravitational potential energy. The reason no government wants you to think about all this is because there is no serious humanitarian response possible to a nuclear explosion. NUCLEAR.

Nuclear devices range from a small portable device carried by an individual to a weapon carried by a … Sometimes "common sense" doesn't cut it as an explanation in science. A nuclear explosion is an explosion that occurs as a result of the rapid release of energy from a high-speed nuclear reaction.The driving reaction may be nuclear fission or nuclear fusion or a multi-stage cascading combination of the two, though to date all fusion-based weapons have used a fission device to initiate fusion, and a pure fusion weapon remains a hypothetical device. Because vision loss is sudden and takes time to recover, flash blindness can be hazardous. That's the same as saying 17x10^6 kilowatts for an hour or 17x10^9 watts for an hour. Flat nuclear bomb in a city. Like. Nuclear weapon - Nuclear weapon - Residual radiation and fallout: Residual radiation is defined as radiation emitted more than one minute after the detonation. What? And to be honest you couldnt even compare nuclear or anything homemade to the sun. Finally, a big ball of orange, the center that was so bright, becomes a ball of orange that starts to rise and billow a little bit and get a little black around the edges, and then you see it's a big ball of smoke with flashes on the inside of the fire going out, the heat. What kind of nuclear explosion? The heat from the explosion is so powerful that it can be felt for miles away, in a "heat blast." ask that question in a million year where we can travel to the sun.
