All waves travel at different speeds in different media. We studied how the speed of light and sound changed in the different states of matter. Tell whether each statement relates to sound or light. Group of answer choices Travels fastest in solids, slower in liquids and slowest in a gas. light (and all EM waves) Travels slowest in solids, faster in liquids and even faster in a gas. sound travels about 340 m/s in air light (and all EM waves) travels at 3 x 10^8 m/s sound Cannot travel through a vacuum. sound Travel the fastest in a vacuum. light (and all EM waves)

sleep paralysis is a parasomnia, events associated with sleep.

sleep paralysis happens when you are in the middle of waking up or falling asleep. it is the feeling of being conscious but unable to move. it definitely involves hallucinations.

i had a friend that had sleep paralysis and he told me a story one time where he was laying in bed and he couldn't move his body no matter how hard he tried and there was someone standing in the corner of his room coming towards him. he couldn't move and you can't "wake up" because you are already conscious. sometimes sleep paralysis can be triggered by frequent waking up during the night based off of multiple trips to the bathroom, or if you had ever been abused, sleep paralysis can start happening from things like that.
