everyday science MCQ #49852

  1. Question 1

    Q1. The mirror formula relating object distance (u), image distance (v), and focal length (f) is:

    • A) 1/f = 1/u - 1/v
    • B) 1/f = 1/u × 1/v
    • C) 1/f = 1/v + 1/u
    • D) 1/f = v - u

    Answer: 1/f = 1/v + 1/u

    Explanation: The mirror formula is 1/f = 1/v + 1/u, where f is the focal length, v is the image distance, and u is the object distance (all measured from the pole of the mirror). This relationship holds for both concave and convex mirrors when sign conventions are applied consistently.
