History Main / SlowLight

* Light actually works this way in-universe in the Literature/{{Discworld}}. It's explained that this is because of the Disc's strong magical field distorting the way physical law works, slowing down light to roughly the speed of sound. In an extreme case, we find out that the Disc's sun[[note]]a ball of flame roughly a mile across orbiting the Disc and the megafaunae which carry it[[/note]] actually travels at twice the speed of its own light ([[LampshadeHanging "this does not appear]] [[HandWave to cause any problems"]]. Indeed, we find that an observer will start seeing a relativistic red/blue frequency shift while travelling in a magically enhanced coach at the unprecedented speed of ''40 miles an hour''.

* ''Series/{{Bones}}'': when Zack shows Booth & Brennan a mirror setup that the Gormagon used to watch the vault, he set off a laser beam that worked its way very slowly around the room.

* [[http://www.ted.com/talks/ramesh_raskar_a_camera_that_takes_one_trillion_frames_per_second.html Femto Fotography]], recording light at a pace of 0.6mm.

** Granted, there is speculated to exist a 'faster kind of light, with which the slow light is seen', but who needs it, if no one can see it?

* Acknowledged in the epilogue of one episode of ''WesternAnimation/MagicSchoolBus'' involving a light-based pinball-like game.

When applied to beam/laser weapons, may overlap with PainfullySlowProjectile and/or FrickinLaserBeams, depending on just how slow the light goes.

* At the conclusion of ''Film/{{Legend}}'', the sunlight takes 20 seconds to reflect off all of the shields and reach the underground chamber where it blows away Darkness.

* In one ScoobyDoo episode, the gang gets locked in an ancient temple. To get out, they need to reflect moonlight onto a symbol on the wall a la LightAndMirrorsPuzzle. However, instead of the light instantly appearing on the wall, we see a ray of light slowly bouncing between the mirrors until it reaches the wall. Worse yet, it misses at first, forcing Scooby to readjust just in time for another pulse of light to slowly move in and be reflected.

Normally, light moves so fast that it seemingly instantly jumps from point A to point B, or at least faster than the eye can follow. Not when this trope comes into action. In this case, you can see light bounce all over the place instead of instantly seeing the new setup.
