You will have to give us the entire problem. Primary ray usually refers to an unreflected or unrefracted ray - the light ray that comes directly from the source.

Thats the entire problem for it. We did a lab for concave and convex mirror and lens to find out if an object distance from a focal point changes the image. We had to write an abstract about it and one of the question he wanted to know is: Explain the significance of the two primary rays and what that means for the general rules for reflection(refraction).
