Answer:
(b) any distant tree
Explanation:
To determine the focal length of a convex lens we put the convex lens in a holder (or stand)and keep it in front of a distant object like a tree so that the rays coming from that trees pass through it.cardboard screen is put behind the lens we change the distance of the screen from the convex lens and clear inverted image of the tree is formed on the screen. measure the distance of the screen from the lens with the screen. this distance will be the focal length of a convex lens.for example if the image of a distant windows form at a distance of 20 cm from a convex lens then the focal length of the convex lens with the 20 CM

Answer:
(d) A well -illuminated distant tree
Explanation:
First of all, the object must be placed at a good distance, so that removes options (a) and (c). Then, the object must be clear for proper image formation. Therefore, it should be well-illuminated.
Thus, the answer is option (d).
