Question

To determine the focal length of a 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) Place a screen opposite to the object on the lab table
(e) Adjust the position of the lens to form a sharp image
The correct sequence of these steps is:
(A) c, a, d, e, b
(B) c, d, a, e, b
(C) c, d, e, a, b
(D) c, a, e, d, b

Answer 1

Answer:

(C)c,d,e,a,b is the answer of the question

Answer 2

(B) c, d, a, e, b

Explanation:

The correct sequence to find the focal length of a convex lens for obtaining a sharp image of a distant object will be as follows:  

(c) Select a well lit distant object.

(d) Place a screen opposite to the object on the lab table.

(a) Adjust the position of the lens to form a sharp image.

(e) Hold the lens between the object and the screen.

(b) Measure the distance between the lens and the screen.

So option B is the correct answer.
