If the image distance is equal to the object distance for a lens, what is the magnification?
Correct Answer: 1
Step 1: Understand the terms 'image distance' and 'object distance'. The image distance (v) is how far the image is from the lens, and the object distance (u) is how far the object is from the lens.
Step 2: Recognize that when the image distance is equal to the object distance, we can say v = u.
Step 3: Use the formula for magnification, which is m = v/u.
Step 4: Substitute v with u in the magnification formula: m = u/u.
Step 5: Simplify the equation: m = 1.
Step 6: Conclude that when the image distance equals the object distance, the magnification is 1.
Magnification in Optics – Magnification (m) is the ratio of the image distance (v) to the object distance (u) for lenses, indicating how much larger or smaller the image is compared to the object.
