Hello. I have a concern in relation to ray diagrams. So I read that the first incidence ray I draw must be parallel to the principle axis and be reflected such that it passes through the principle axis. Ok so this part isnt too much of a worry. However it states that the second ray must be drawn from the top of the object through the principle axis and reflected parallel to the principle axis. I know that this is only possible when the object is placed infront of the principle focus (i.e. further away from the pole) I know that when the object is closer to the pole then the principle focus that the image is virtual. In this case Ive seen the 2nd incidence ray drawn to be either going through the pole OR being drawn such that it follows the dotted (virtual lines) that are drawn through the focus. which is correct? or are they situational. Cheers!
