a light ray approaches a measure at an angle 22 degrees with the mirror surface. what is the angle of reflection of this light ray?​

Note: Angle of reflection is the angle the ray makes with the Normal of the Mirror and NOT the Mirror Surface

Since the ray makes an angle of 22° with the Mirror surface

The angle it'll make with the Normal is 90-22(Because both are orthogonal)

So

Angle of Incidence = 90-22 = 68°

From the Law of Reflection

Angle of Incidence = Angle of Reflection

So

Angle of reflection = 68°

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.
