To determine which option best describes the type of lens shown in the ray diagram, we need to recall the properties of concave and convex lenses:
-
Concave Lens:
- Always produces virtual images that are upright and smaller than the object.
- The image is formed on the same side as the object, not the opposite side.
-
Convex Lens:
- Can produce both real and virtual images depending on the position of the object relative to the focus point.
- If the object is beyond the focal point, a real and inverted image is formed on the opposite side of the lens. If the object is within the focus, a virtual image is formed on the same side as the object.
Given the descriptions in your options:
- Options describing a concave lens are incorrect in stating that "the image is always on the opposite side of the lens as the original object."
- The accurate descriptions of a convex lens include the remark about image position depending on the object's position relative to the focus.
Therefore, if the ray diagram indeed shows a convex lens, the appropriate choice would be:
"It shows a convex lens. For this type of lens, the image position depends on the object's position relative to the focus point."
If the diagram instead represented a concave lens, then the first two options would be incorrect as well. Make sure to analyze the ray diagram for confirmation.
