Solution

To find the distance (s') from the image to the lens, you can use the lens formula which is 1/f = 1/s + 1/s'. Here, f is the focal length of the lens, s is the object distance, and s' is the image distance.

Step 1: Identify the given values. You need to know the focal length of the lens (f) and the object distance (s).

Step 2: Substitute the given values into the lens formula.

Step 3: Solve the equation for s'. This will give you the image distance.

Step 4: If s' is positive, the image is real and on the opposite side of the lens from the object. If s' is negative, the image is virtual and on the same side of the lens as the object.

Step 5: Express your answer in the appropriate units. The unit of distance in the lens formula is typically meters (m), but it could be any unit of length, depending on the units used for the given values.

Please note that without specific values for f and s, I can't provide a numerical answer.
