Hey!!!!!!!!!!!
The rules for drawing the ray diagrams are simple.....
*There should be a lens(be it concave ,convex or any other)
*Should draw an object on right or left side of the object.
*Draw a minimum of two(must) rays starting from a single point(top of the object).
#If the rays are parallel,then the rays will converge at the focus on the other side(if it is convex) or appears to diverge from the focus on the other side(if it is concave)
#If the ray is passing through the optical centre no deviation takes place.
#If the ray passes through the focus(convex) or is directed towards the focus(concave) then after refraction the ray goes parallel to the lens.
*Join the two rays to form the image.
The nature and position of the image depend on the lens used and position of the object.
Hope this is helpful to you......
If you have any queries ask me.
