Questions & Step-by-Step Solutions

What is the magnification produced by a lens if the object distance is 15 cm and the image distance is 45 cm?
  • Step 1: Identify the object distance (u) and the image distance (v). Here, object distance is 15 cm and image distance is 45 cm.
  • Step 2: Write down the formula for magnification (m), which is m = image distance (v) / object distance (u).
  • Step 3: Substitute the values into the formula: m = 45 cm / 15 cm.
  • Step 4: Perform the division: 45 divided by 15 equals 3.
  • Step 5: Conclude that the magnification produced by the lens is 3.
