A wave
Challenge Question: If Avari said that if she sees herself in a mirror, it's called reflection. Is she correct? Yes or No?
Yes, she is reflected off the mirror, causing her to see herself.

Challenge Question: Jalnqua said that when the door handle of his front door got hot, it was because of refraction. Is he correct? Yes or no?
No, the door handle became hot due to the process of absorption of the Sun's light rays
