What is the magnification produced by a concave mirror if the object distance is 10 cm and the image distance is 5 cm? (2019)
  • Step 1: Identify the formula for magnification produced by a mirror, which is m = -v/u.
  • Step 2: Understand the variables: v is the image distance and u is the object distance.
  • Step 3: Substitute the given values into the formula. Here, v = -5 cm (since the image is real and on the same side as the object) and u = -10 cm (the object distance is taken as negative in mirror formula).
  • Step 4: Plug in the values: m = -(-5)/(-10).
  • Step 5: Simplify the equation: m = 5/10.
  • Step 6: Calculate the final result: m = 0.5.
