Real image versus virtual image – Convex mirror
The image formed from a convex mirror is always upright, diminished (smaller) and virtual regardless of where the object is placed.
We need to explain virtual image.
The main difference between a real image and virtual image is:
A REAL IMAGE CAN BE DISPLAYED ON A SCREEN
A real image can be displayed on a screen or piece of paper or on a wall whereas a virtual image can not.
A virtual image can be seen with the eyes but it's impossible to display the image on a screen.
Your eye can see an image of the original object in the mirror. The image will be upright, diminished and because that image can not be captured on a screen it is virtual.
With mirrors and lenses:
REAL IMAGES – ALWAYS INVERTED
VIRTUAL IMAGES – ALWAYS UPRIGHT
A real image is always inverted (put upside down) whereas a virtual image is always upright.
