where do the three rays in a ray diagram start?\no at a focal point on the opposite side of the lens\no at three different points on the object\no at a focal point on the same side of the lens\no at a single point on the object

where do the three rays in a ray diagram start?\no at a focal point on the opposite side of the lens\no at three different points on the object\no at a focal point on the same side of the lens\no at a single point on the object

Answer

Brief Explanations:

In a ray diagram for lenses (in optics), the three rays used to locate the image start from a single point on the object. This is a fundamental principle in constructing ray diagrams for lenses. For example, when dealing with a convex or concave lens, we consider rays emanating from one point (say the top of an object) to find where the image of that point is formed.

Answer:

at a single point on the object
