To obtain a sharp image of a burning candle placed at the farther end of a laboratory table, on a screen using a concave mirror, the student would have placed the screen at the focal length of the mirror. However, to get a better value of the focal length of the mirror, the student should follow the steps given below:
Step 1: Move the mirror slightly towards the screen
- By moving the mirror slightly towards the screen, the image of the candle will move away from the screen.
- The size of the image will also decrease.
Step 2: Observe the new image
- The student should observe the new image formed on the screen.
- If the image formed is sharp and clear, it means that the mirror has been moved to a position closer to its new focal length.
- If the image formed is not clear, the student should repeat the process by moving the mirror further towards the screen.
Step 3: Measure the distance between the mirror and the screen
- Once the student has obtained a clear image of the candle, he should measure the distance between the mirror and the screen.
- This distance would give him the new focal length of the mirror.
Therefore, the correct answer is option 'A'. The student should move the mirror slightly towards the screen to obtain a better value of the focal length of the mirror.
Step 1: Move the mirror slightly towards the screen
- By moving the mirror slightly towards the screen, the image of the candle will move away from the screen.
- The size of the image will also decrease.
Step 2: Observe the new image
- The student should observe the new image formed on the screen.
- If the image formed is sharp and clear, it means that the mirror has been moved to a position closer to its new focal length.
- If the image formed is not clear, the student should repeat the process by moving the mirror further towards the screen.
Step 3: Measure the distance between the mirror and the screen
- Once the student has obtained a clear image of the candle, he should measure the distance between the mirror and the screen.
- This distance would give him the new focal length of the mirror.
Therefore, the correct answer is option 'A'. The student should move the mirror slightly towards the screen to obtain a better value of the focal length of the mirror.

As the image distance increases, the object distance would decrease thus the distance between the mirror and the screen should be decreased. so, he should move the mirror slightly towards the screen.
