how bright is a nuclear explosion

NUCLEAR. 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. 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. What? 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. 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. the sun really doesn't seem very bright, its a tiny star and we're 93 million miles away and its completely perfect. 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. During a nuclear explosion, dirt, debris and other particles are forced upward into the atmosphere in a giant cloud. Save. There is no bright side to nuclear weapons. Flat nuclear bomb in a city. The reason no government wants you to think about all this is because there is no serious humanitarian response possible to a nuclear explosion. In that case, a nuclear explosion (of a fission device, I'm given to understand) is briefly hotter than the Sun (the number I found quotes "tens of millions of degrees"). If the intensity is great enough, a permanent retinal burn (photic retinopathy) will result."[7]. Like. What kind of nuclear explosion? 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. However, if the eyes are exposed to a high enough level of light, such as a nuclear explosion, the blindness can become permanent. The EMP was so strong that it darkened street lights in Hawaii, made navigation systems go haywire, and even tampered with nearby satellite systems. The best answer for this question is completely wrong. um......... i always haeard how bright it was and that you would get blinded from miles aways, but i'm not sure how bright it actually is. Flash blindness is an either temporary or permanent visual impairment during and following exposure of a varying length of time to a light flash of extremely high intensity, such as a nuclear explosion, flash photograph, or extremely bright light, i.e. ... To this day, the explosion remains the largest nuclear bomb … Sometimes "common sense" doesn't cut it as an explanation in science. EXPLOSION. Three days later, a second bomb detonated over Nagasaki. It is unclear whether pain is directly associated with flash blindness. freepik. [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. Radioactive Fallout. Assuming no friction and neglecting air resistance, -? As the question stands, the answer's "yes", "no", and "maybe" - because the truth of the matter is, we're not sure how hot the Sun is inside. Flat bright nuclear explosion effect. The heat from the explosion is so powerful that it can be felt for miles away, in a "heat blast." 324 19. Like. The explosion's mushroom cloud stretched 40 kilometers into the sky, dispersing nuclear fallout across thousands of square kilometers in the Pacific. A nuclear explosion may occur with a few . [1] The bright light overwhelms the retinas of the eyes and generally gradually fades, lasting anywhere from a few seconds to a few minutes. "Laser Pointers: Their Potential Affects [sic] on Vision and Aviation Safety (April 2001)FAA", first strike(DOD) The first offensive move of a war. "[4] The United States Federal Aviation Administration in Order JO 7400.2 defines flash blindness as "generally, a temporary visual interference effect that persists after the source of the illumination has ceased."[5]. Take a class in physics and you will realize what an ignorant answer you posted for idiots to base their research on. to be honest you cant compare anything to our sun cuz it is impossible to calculate the brightness scale because the sun is too hot (melt anything that we throw at it). If the fission explosion is an airburst, the residual radiation will come mainly from the weapon debris. is it brighter than other stars such as ................dunno, vy canis majoris? But if the duration of the power producing explosion is 1 millionth of an hour, the power would be 17x10^15 watts. For example, the subject of a flash photograph can be temporarily flash blinded. 174 9. As the nuclear explosion begins, the bomb and all of its components are heated to extremely high temperatures of around ten million kelvin. What is its gravitational potential energy. Like. Whether or not it's possible for light to bend around the curvature of the Earth? The initial explosion creates a nuclear flash. The first thing you'd see if a nuclear bomb exploded nearby is a flood of light so bright, you may think the Sun blew up. You may also like. The nuclei of certain light atoms will fuse together spontaneously with an accompanying release of energy, if they approach very close to one another. Because vision loss is sudden and takes time to recover, flash blindness can be hazardous.
