Answer» \t
Concave Vs Convex
AppearanceA concave lens is thinner in the middle and thicker at the edges.A convex lens is thicker in the middle and thinner at the edges.Also known asIt is also known as Diverging LensIt is also known as Converging LensApplicationUsed in glasses, some telescopes, spy holes in the doors, etc. It is also used for the correction of the problem in short sightUsed in the camera, focus sunlight, overhead projector, projector microscope, simple telescope, magnifying glasses, etc. It is also used for the correction of the problem in long sight.Focal LengthNegative Focal LengthPositive Focal LengthIncident RaysIt diverges the incident rays away from the principal axis.It converges the incident rays towards the principal axis.Type of Image FormedThe image formed is an upright, virtual, and smaller size than the object. The position of the image formed is in between the lens and the object regardless of the object’s positionThe image formed is inverted, real and smaller than the object when the object is placed at focus. The image formed is the inverted, real, and the same size as the object when the object is placed at 2F. The image formed is inverted, real and larger than the object when the object is placed between 2F and F. No image is formed when the object is placed at focus (F). The image formed is upright, virtual, and larger than the object when the object is placed on the same side of the lens.\t
