Step 1: Understanding the Concept: 
Virtual images are formed when light rays appear to diverge from a point behind the mirror or lens. Unlike real images, they cannot be projected onto a screen. 
Step 2: Key Characteristics: 
Virtual images are always upright (erect). 
They are usually smaller (as in convex mirrors) but can also be larger (as in magnifying lenses). 
They appear behind the reflecting/refracting surface. 
Step 3: Examples: 
Image in a plane mirror $\rightarrow$ always virtual and erect. 
Image in a convex mirror $\rightarrow$ always virtual, erect, and diminished. 
Step 4: Final Answer: 
A virtual image always appears Erect.
