To determine the focal length of convex lens by obtaining a sharp image of a distant object we generally follow the following steps which are not in proper sequence.
(a) Hold the lens between the object and the screen
(b) Measure the distance between the lens and the screen
(c) Select a well lit distant object
(d) Adjust the position of the lens to form a sharp image
The correct sequence will be:​
  • a)
    c, a, d, b
  • b)
    c, d, b, a
  • c)
    a, c, d, b
  • d)
    c, d, a, b
Correct answer is option 'A'. Can you explain this answer?

Correct sequence to determine the focal length of a convex lens:

1. Select a well-lit distant object: The first step is to choose a distant object that is well-lit. This could be a building, a tree, or any other object that is far away and easy to focus on.

2. Hold the lens between the object and the screen: Once the object is selected, hold the convex lens between the object and the screen. The lens should be positioned in such a way that it is equidistant from both the object and the screen.

3. Adjust the position of the lens to form a sharp image: Next, adjust the position of the lens until a sharp image of the distant object is formed on the screen. This can be achieved by moving the lens closer to or farther away from the screen. The lens should be moved back and forth until the image on the screen appears clear and focused.

4. Measure the distance between the lens and the screen: Once a sharp image is obtained, measure the distance between the lens and the screen. This distance is known as the focal length of the convex lens.

Therefore, the correct sequence to determine the focal length of a convex lens is:
c) Select a well-lit distant object
a) Hold the lens between the object and the screen
d) Adjust the position of the lens to form a sharp image
b) Measure the distance between the lens and the screen

It is important to follow these steps in the given sequence to obtain an accurate measurement of the lens's focal length.
