Answer:
Explanation:
When the two rays of light actually meets after refraction from a lens, the image is said to be real.
When the two rays of light appears to meet after refraction from a lens, the image is said to be virtual.
A concave lens always forms a virtual image, because it diverge the rays of light.
A convex lens forms a real image when the object placed between infinity and the focus of lens but t forms a virtual image when the object is placed between optical centre and the focus of the lens.
