Convex lens forms initial image, then concave lens alters rays to form final image right of the second lens.
To draw a qualitative principal ray diagram for the given lens system, follow these steps:
1. Convex Lens (first lens):
Place the convex lens with a focal length of 3.00 cm at the leftmost side of the diagram.
Draw an arrow or object representation 4.50 cm to the left of the convex lens to depict the object. Label it as "Object."
2. Principal Rays:
Draw two principal rays from the tip of the object arrow:
The first ray parallel to the lens axis (parallel to the optical axis) should pass through the focal point on the right side of the convex lens.
The second ray that passes through the optical center of the lens travels undeviated.
3. Convex Lens Image Formation:
Where these two rays intersect after passing through the convex lens, draw an arrow or an image representation. Label it as "Image."
4. Concave Lens (second lens):
Place the concave lens with a focal length of 6.50 cm to the right of the convex lens.
Draw a continuation of the principal rays from the image formed by the convex lens.
The ray that passed through the optical center of the convex lens continues undeviated.
The other ray, which passed through the focal point of the convex lens, will emerge parallel to the lens axis after passing through the concave lens.
5. Final Image Formation:
The point where these rays intersect after passing through the concave lens will represent the final image formed by the entire lens system. Label it as "Final Image."
Ensure that the distances and angles between the lenses, object, focal points, and image are consistent with the given parameters to create a clear and accurate qualitative principal ray diagram of the lens system.
