In a lens diagram, what does "u" mean?

• Object distance

• Image distance

• Focal Point

• Focal Length

Looking at the diagram, describe the object distance.

• u>2f

• u=2f

• u=f

• f<u<2f

Looking at the diagram, describe the object distance.

• u>2f

• u=2f

• f<u<2f

• u=infinity

When the object is between F and 2F (f<u<2f), what type of image is formed?

• Reel

• Real

• Virtual

• Vertical

When the object is at F (u=f), what is the orientation of the image?

• Upright

• Inverted

• Diagonal

• 3-dimentional

When the object is beyond 2F (f<u<2f), what is the image distance (v)?

• v=2f

• v>2f

• v<2f

• f<v<2f

It is a visual defect where the person sees near image as blurry.

• Myopia

• Utopia

• Sophia

This happens when the eyeballs are too long or the eye lenses are too thick
