MCQ
A defective eye cannot see close objects clearly because their image is formed:
  • A
    On the eye lens
  • B
    Between eye lens and retina
  • C
    On the retina
  • D
    Beyond retina
✓

Answer

  1. Beyond retina

Explanation:

A defective eye cannot see close objects clearly because its image is formed beyond the retina.

This defect is known as farsightedness.

Here rays from near objects could not be converted at the retina due to focal length of the eye lens could not be decreased, so, image is formed beyond the retina.

A student has obtained an image of a well-illuminated distant object on a screen to determine the focal length, $\text{F}_{1}$  of the given spherical mirror. The teacher then gave him another mirror of focal length, $\text{F}_{2}$  and asked him to obtain a focussed image of the same object on the same screen. The student found that in order to focus the same object using the second mirror, he has to move the mirror away from the screen. From this observation it may be concluded that both the spherical mirrors given to the student were (select the correct option)
