- Jet Fuel, JP-5, JP-8 DFM: Properties, Chemical Composition . . .
They contain hundreds of hydrocarbons as well as many additives The actual composition of any given fuel varies depending upon source of the crude oil, refinery processes, and product specifications The hydrocarbons in jet and diesel fuels are less volatile than those in gasoline JP-5 is a high-flash-point jet fuel developed by the Navy
- Strange white flash in a dark room - II - Physics Forums
Even comparatively dim flashes could appear bright when your eyes are in that situation Even though the flash itself might only last a tiny fraction of a second, the image sensed by your retina (which can include the walls floor ceiling -- anything lit by the flash) might last at least a little longer than that, just due to the way the eyes work
- Unexplained bright flash of light inside house - Physics Forums
From the video, the initial flash was very short, showing up at full brightness only for two frames (although it was preceded by a couple of frames showing a partial flash) Frames seem to be 30 per second, so that makes the flash duration between a 30th and a 10th of a second (You can use comma and period on the keyboard to step back or forward)

- How to calculate flash point of mixture? - Physics Forums
However, if you Google something like "Effect of Additives on the Flash Point of Flammable Liquid" you will find that you can begin by adding water to the alcohol to raise its flash point (for example, a mixture of 7 water 3 methanol seems to raise the flash point by 25 degrees C) You would then add this mixture to the petroleum
- How Does a Grenades Shockwave Cause Fatal Injuries? - Physics Forums
Stun grenades, or "flash bang" grenades, operate on this principle They produce a large blast but almost no shrapnel The noise and brightness of the flash are very disorienting, and the shock wave can actually knock a person down, but the chances of being killed by one, even at close proximity, are very slim
- Debunking the Myth: Do LED Lights Flicker? Get the . . . - Physics Forums
Many LED bulbs produce flicker - a rapid switching between on and off states Because the flickering happens at a very fast rate - typically 120 times per second or faster - it is not immediately observable to humans and appears to us as a light bulb of steady and constant brightness
- The Interaction of Sound and Light - Physics Forums
Sonoluminescence, from the Latin for sound and light, is a phenomenon that involves a collapsing bubble emitting a flash of light I used to be a bubble scientist so this is one of my favorite effects; I have written about it before on PhysicsForums and on my blog Sound waves, when applied to a bubbly fluid, cause the bubbles to expand and
