Convex Lens is Converging

A concave lens is called a diverging lens because rays parallel to the principal axis appear to diverge from the focal point 2. The second focal point for a convex lens is a point F.

If the equation shows a negative image distance then the image is a virtual image on the same side of the lens as the object.

. For a convex lens the first focal point is a point F 1 on the principal axis of the lens such that the rays of light starting from it or passing through it after refraction through lens become parallel to the principal axis of the lens. A convex lens of focal length 10 cm is placed at a distance of 12 cm from a wall. This lens formula is applicable to both the concave and convex lenses.

Spherical Lenses C1 A convex lens is called a converging lens because rays parallel to the principal axis converge at the focal point. If this equation shows a negative focal length then the lens is a diverging lens rather than the converging lens. A light ray can pass through a lens from either direction.

An object is placed at a distance of 100 cm from a converging lens of focal length 40 cm. The shapes of biconvex and biconcave spherical lenses are illustrated in Fig. A convex lens.

Therefore a lens has two principal foci. What is the nature and position of the image. Answer v6667 cm behind the lens m-0667 real and inverted.
