Answer 2

Calculation of the Distance to Place the Screen for a Clear Image

To determine the distance at which the screen should be placed to obtain a clear image of the candle, we can use the lens formula:

1/f = 1/v - 1/u

Where: - f is the focal length of the lens - v is the image distance from the lens - u is the object distance from the lens

In this case, the object distance (u) is given as 25 cm, and the optical power (P) of the lens is given as 10 Dptr (diopters). The optical power of a lens is defined as the reciprocal of the focal length in meters:

P = 1/f

Therefore, we can calculate the focal length (f) of the lens as follows:

f = 1/P

Let's calculate the focal length first.
