Hello, the answer is:
Plane mirror - The image formed by a plane mirror is always upright, virtual and the same size as the object no matter where the object is placed in front of the mirror. ... Convex mirror – The image formed by a convex mirror is always upright, virtual and diminished no matter the distance of the object from the mirror
Yes it’s good! Bellow 500 I believe wouldn’t be considered good
Good things come back around and most myths have morals or hidden messages in them
Hope this helps Good Luck! :)
