If the 2 rays do not intersect, draw dotted lines backwards and it will intersect. This situation is known as a virtual image, since the light rays did not reach the image. The image is upright, enlarged and on the same side to the object (meaning it is at the same side as the lense)

# data[].attributes.body
The lense is the centre vertical line. The axis is the centre horizontal line. The image is real, diminished, inverted and opposite side to the object (meaning it is not at the same side as the lense)

A ray diagram is constructed to find out

the height of an image

whether the image is upright or inverted

whether the image is diminished or enlarged

where is the image positioned

whether or not the image is real or virtual

To draw a ray diagram, draw 2 rays. One passing through the centre of the lens and one parallel to the axis, then passing through the focal point, F.

# data[].attributes.body
The focal point is the point where light rays coming from far meet.
The focal length is the distance from the centre of the lense to the focal point

# data[].attributes.body
The point where light rays meet is known as the focal point.
This lense, thicker in the middle is called a converging lense. Lenses that are thinner in the middle are called diverging lenses
