Question

List in proper sequence the steps of the experiment for determining the approximate focal length of a given concave mirror by obtaining the image of a distant object

Answer 1

Answer:

The steps are given below :

Explanation:

1. Adjust concave mirror to mirror holder and locate it on table.
2. Turn the mirror's face in the direction of a far-off object (a candle in this case). The chosen object need to be seen with your naked eyes.
3. Modify the position of the screen in such a way that it forms a clear image of the candle on the screen.
4. Measure the distance between the concave mirror and the screen with a meter scale.  
5. Record your observations in calculation & observation table.  
6. Repeat this procedure two - three times and find the average of the focal length.​

Answer 2

Answer:

here is your answer

Explanation:(i) Fix the concave mirror on the stand and place it on table facing towards a distant object.

(ii) Arrange the screen on the table so that the image of distant object is obtained on it.

(iii) Measure the distance between the mirror and the screen using a metre scale. This distance is the focal length (F) of the mirror.
