Drawing Ray Diagram to produce a virtual image for a convex lens
The convex lens is represented by a vertical line with the arrows pointing outwards. The position of the object is added onto the diagram, this should be located between the lens and F.
From the object draw a diagonal ray line that passes through the centre of the lens as shown below.
Now draw a horizontal ray line from the object to the concave lens as shown below.
A diagonal line is now drawn from the lens, through F on the right hand side.
An image of an eye is used to show where the light rays go at the end of these rays
Now extend both of the diagonal lines backwards until they meet, this time use a dotted line.
Draw in the virtual image arrow it should point from the horizontal line upwards towards where the dotted lines meet.
The diagram is now complete. The image formed is virtual, upright and larger than the object.
There are no practice questions here, but you should definetly practice drawing this.
