At the focal point of a converging lens, the object:

A. appears inverted

B. can be seen normally

C. appears reversed (left/right)

D. cannot be seen

A. appears inverted

B. can be seen normally

C. appears reversed (left/right)

D. cannot be seen

Answer:D. cannot be seen

Explanation:Answer:D) Image cannot be seen

Explanation:As we know by lens formula

[tex]\frac{1}{d_i} + \frac{1}{d_o} = \frac{1}{f}[/tex]

now we know that

object is placed at the focal point of lens

[tex]d_o = f[/tex]

so we will have

[tex]\frac{1}{d_i} = 0[/tex]

so the image will form at infinite

so image will be at infinite distance from the lens

so it cannot be seen
