Four students A, B, C and D did their experiment on finding the focal length of convex lens by obtaining the image of a distant object as follows:
Student A used the window grill in the laboratory as the object and a white paper sheet held in hand, as the screen.
Student B used a distant tree in absence of sunlight as the object, and a white thick board held on a stand, as the screen.
Student C used a well illuminated laboratory window grill as the object and a white paper sheet held on a stand as the screen.
Student D used a well illuminated distant tree as the object and a white thick board held on a stand, as the screen.
Arrange these techniques in order of decreasing accuracy in measurement.

The order of decreasing accuracy in measurement of focal length of convex lens by the given techniques is DBCA.
D - Student D used a well illuminated distant tree as the object and a white thick board held on a stand, as the screen. This technique is more accurate than Student A's technique because the object is a distant tree, which provides a nearly parallel beam of light, and the screen is held on a stand.
B - Student B used a distant tree in absence of sunlight as the object, and a white thick board held on a stand, as the screen. This technique is also quite accurate as the object is a distant tree, which provides a nearly parallel beam of light, and the screen is held on a stand.
C - Student C used a well illuminated laboratory window grill as the object and a white paper sheet held on a stand as the screen. This technique is more accurate than Student B's technique because the object is well-illuminated and the screen is held on a stand, which minimizes any movements or vibrations that could affect the measurement.
A - Student A used the window grill in the laboratory as the object and a white paper sheet held in hand, as the screen. This technique is the least accurate because the object is the window grill in the laboratory, which may not provide a sufficiently distant or parallel beam of light, and the screen is held in hand, which could lead to some movements and vibrations that could affect the measurement.

Order of decreasing accuracy in measurement:
1. Student B: Using a distant tree as the object and a white thick board held on a stand as the screen.
- Student B's technique involves using a distant object, which helps in obtaining a clear and focused image on the screen.
- The use of a white thick board held on a stand as the screen ensures that the image is bright and well-defined.
- This method provides accurate results as it eliminates any potential errors caused by using a nearby object or a handheld screen.
2. Student D: Using a well-illuminated distant tree as the object and a white thick board held on a stand as the screen.
- Student D's technique is similar to Student B's, but the only difference is that the object used is a well-illuminated distant tree.
- This method also provides accurate results as it eliminates errors caused by using a nearby object or a handheld screen.
- However, the slight decrease in accuracy compared to Student B may be due to the varying illumination conditions of the tree.
3. Student C: Using a well-illuminated laboratory window grill as the object and a white paper sheet held on a stand as the screen.
- Student C's technique involves using a well-illuminated laboratory window grill as the object and a white paper sheet held on a stand as the screen.
- While this method may still provide reasonably accurate results, it is not as accurate as using a distant object like a tree.
- The use of a well-illuminated object helps in obtaining a clear image, but the use of a paper sheet as the screen may not provide the same level of brightness and definition as a white thick board.
4. Student A: Using the window grill in the laboratory as the object and a white paper sheet held in hand as the screen.
- Student A's technique involves using the window grill in the laboratory as the object and a white paper sheet held in hand as the screen.
- This method is the least accurate among the given techniques because it involves using a nearby object and a handheld screen.
- The proximity of the object may result in a less focused image, and the use of a handheld screen may introduce errors such as movement or inconsistency in holding the screen.
Therefore, the correct order of decreasing accuracy in measurement is B, D, C, A.
1. Student B: Using a distant tree as the object and a white thick board held on a stand as the screen.
- Student B's technique involves using a distant object, which helps in obtaining a clear and focused image on the screen.
- The use of a white thick board held on a stand as the screen ensures that the image is bright and well-defined.
- This method provides accurate results as it eliminates any potential errors caused by using a nearby object or a handheld screen.
2. Student D: Using a well-illuminated distant tree as the object and a white thick board held on a stand as the screen.
- Student D's technique is similar to Student B's, but the only difference is that the object used is a well-illuminated distant tree.
- This method also provides accurate results as it eliminates errors caused by using a nearby object or a handheld screen.
- However, the slight decrease in accuracy compared to Student B may be due to the varying illumination conditions of the tree.
3. Student C: Using a well-illuminated laboratory window grill as the object and a white paper sheet held on a stand as the screen.
- Student C's technique involves using a well-illuminated laboratory window grill as the object and a white paper sheet held on a stand as the screen.
- While this method may still provide reasonably accurate results, it is not as accurate as using a distant object like a tree.
- The use of a well-illuminated object helps in obtaining a clear image, but the use of a paper sheet as the screen may not provide the same level of brightness and definition as a white thick board.
4. Student A: Using the window grill in the laboratory as the object and a white paper sheet held in hand as the screen.
- Student A's technique involves using the window grill in the laboratory as the object and a white paper sheet held in hand as the screen.
- This method is the least accurate among the given techniques because it involves using a nearby object and a handheld screen.
- The proximity of the object may result in a less focused image, and the use of a handheld screen may introduce errors such as movement or inconsistency in holding the screen.
Therefore, the correct order of decreasing accuracy in measurement is B, D, C, A.
