I am having problems responding to so many equations in Optics. Please help.

optices is basically not easy ,but we have to make it easy by understanding. the understanding of ray optices by formation image means where the image formation takes place , the formation in between the center of curvature and focus or benyod the center of curvature or before center of curvature. by understanding the above types that will give very to solve problems on it. so please refer that.
