Question

02-
The image of an object appears to be blurred and fuzzy if it is located at:
а)25m
b) More than 25cm
C)Less than 25m
d) Any where beyond 5cm

Answer 1

Answer:

(c) Less than 25 cm

Explanation:

We cannot clearly see an object kept at a distance less than 25cm from the eye. This is because ciliary muscles of our eyes are unable to contract beyond certain limit. If the object is placed at a distance less than 25cm from the eye, then the object appears blurred because light rays coming from the object meet behind the ratina.
