Definition of focal point, F for concave lens
The focal point, F is a point on the principal axis, where light rays parallel to the principal axis converge after passing through the lens
Definition of focal point, F for cancave lens
The focal point, F is a point on the principal axis, where light rays parallel to the principal axis appear to diverge from it after passing through the lens
Definition of focal length, ƒ
The distance between the focal point, F and the optical centre
Definition of object distance, u
The distance between the object and the optical centre
Definition of image distance, ν
The distance between the image and the optical centre
Method for drawing ray diagrams for convex lens (1)
A light ray parallel to the principal axis refracts and passes through the focal point, F
Method for drawing ray diagrams for convex lens (2)
A light ray heading towards the optical centre continues in a straight line through the optical centre without refracting
Method for drawing ray diagrams for concave lens (1)
A light ray parallel to the principal axis refracts and appears to come from the focal point, F
Method for drawing ray diagrams for concave lens (2)
A light ray heading towards the optical centre continues in a straight line through the optical centre without refracting
