Question

section (A): Light from a distant object arriving at the eye lens may get converged at a point in front
lezam ): The eye is producing too much divergence in the incident beam.​

Answer 1

Answer:

Focal length (shown in red) is the distance between the center of a convex lens or a concave mirror and the focal point of the lens or mirror — the point where parallel rays of light meet, or converge.

Answer 2

Assertion :- Light from a distant object arriving at the eye lens may get converged at a point in front.

Assertion is true but its reason is not the correct explanation of assertion due to the following reasons:

- The distance between the centre of centre of convex lens of the concave mirror is called focal length.

- The point where parallel rays of light converge or meet is called Focal Point of the mirror or lens.

- Here, in assertion the condition is short sightedness as the light from the distant object arriving at eye lens make it convert at a point from the retina.

- But the lens is converging more i.e. yhe convex lens. It can be corrected by using diverging lens or the concave lens.
