The focal length of the lens is 0.2, the distance from the object to the lens is 0.6. where will the image be?

To determine the value of the distance from the image to the lens taken, we use the formula: 1 / F = 1 / d + 1 / f, whence 1 / f = 1 / F – 1 / d = (d – F) / (F * d) and f = F * d / (d – F).

Values of variables: F – focal length of the taken lens (F = 0.2 m); d is the distance from the taken lens to the object (d = 0.6 m).

Let’s perform the calculation: f = F * d / (d – F) = 0.2 * 0.6 / (0.6 – 0.2) = 0.3 m.

Answer: The distance from the image to the taken lens is 0.3 m.
