Q: What happens to the image distance when the object distance is doubled in a concave mirror? (2023)
Solution: In a concave mirror, if the object distance is doubled, the image distance also changes according to the mirror formula, leading to a doubling effect.
Steps: 5
Step 1: Understand the mirror formula, which is 1/f = 1/do + 1/di, where f is the focal length, do is the object distance, and di is the image distance.
Step 2: Identify the initial object distance (do) and calculate the initial image distance (di) using the mirror formula.
Step 3: Double the object distance (do) to get the new object distance (do').
Step 4: Substitute the new object distance (do') into the mirror formula to find the new image distance (di').
Step 5: Compare the new image distance (di') with the original image distance (di) to see how it has changed.
