Question

convex lens always form virtual image when an object is placed at any point on principle axis.why? explain?​

Answer 1

Answer:

Convex mirror always forms a virtual image of a real object. Real lenses show distortions due. The ray parallel to theprincipal axis passes through the focalpoint after refraction by the lens. ... This is because of the geometry of how the light rays bounce off of concave (realimage) or convex (virtual image) surfaces.
