list in proper sequence the steps of experiment for the deter determining the approximate focal length of a given concave mirror by obtaining the image of a distant object
Answers
1-7 steps are given in the attachment...
Additional steps-
8) Note down all the observations.
9) Find out the average of all the observations.
Hence we find our required focal length.
Answer:
The steps are given below :
Explanation:
Adjust concave mirror to mirror holder and locate it on table.
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.
Modify the position of the screen in such a way that it forms a clear image of the candle on the screen.
Measure the distance between the concave mirror and the screen with a meter scale.
Record your observations in calculation & observation table.
Repeat this procedure two - three times and find the average of the focal length.
