Despite any zooms and explosions you may have heard in movies about outer space, sound actually can’t travel through empty space. The molecules that make up these objects help the sound travel.
Q. What physics mistake happens when you see and hear an explosion in outer space in a science fiction film?
To travel to us from outer space, the wave must be able to travel through regions of space which are essentially vacuum (nothing there). Sound cannot do this, as it requires a medium to propagate in, so we would not be able to hear the explosion. This is one mistake.

Q. What two physics mistakes occur in a science fiction movie that shows in outer space a distant explosion that you see and hear at the same time?
What two physics mistakes occur in a science fiction movie when you see and hear at the same time a distant explosion in outer space? Space is a vacuum so the explosion has no sound and light travels faster than sound so we would see the explosion long before we heard it.
Q. What two physics mistakes occur in a science fiction movie that shows a distant explosion in outer space where you see and hear the explosion at the same time 1 the explosion Cannot occur in outer space if it could the faster moving light would reach you?
What two physics mistakes occur in a science fiction movie that shows a distant explosion in outer space, where you see and hear the explosion at the same time? First, in outer space there is no air or other material to carry sound. Second, if there were, the faster-moving light would reach you before the sound.
Q. Why do you notice smoke from the starter’s gun before you hear it fire?
Light travels faster than sound. In the stands of a race track you notice smoke the starters gun before you hear fire. Speed of sound is slow compared to the enormous speed of light.
Q. Why does light travel faster in water?
Light travels faster than sound even in water. Light waves are electromagnetic transversal waves. They can travel through a vacuum and any particles they contact slow them down. So when they move through denser water they are slowed down more.
Q. Why does light travel slower in glass?
Electromagnetic waves simply travel slower through glass than through air. So the wave crests are closer to each other, but the light still oscillates the same number of times per second. When light goes through glass, it gets knocked around and bumps into all sorts of molecules and electrons.
Q. Does light slow down in refraction?
The light bends towards the normal line. If light travels enters into a substance with a lower refractive index (such as from water into air) it speeds up. The light bends away from the normal line. A higher refractive index shows that light will slow down and change direction more as it enters the substance.
Q. What color of light bends the most?
violet light
Q. Can you slow down a photon?
The photons themselves do not slow down. But their passage through a medium involves absorption by electrons and re-emission. For some materials such as water, light will slow down more than electrons will.
