Answer 1

Answer:

Explanation:

procedure:

4. light a candle and ask your friend to take the candle far away from the lens along the principal axis

5.adjust a screen(a sheet of white paper placed perpendicular to the axis)which is on the other side of the lens until you get an image on it.

6. measure the distance of the image from the v-stand of lens and also measure the distance between the candle and stand of lens.

7. record the values
