What is the magnification produced by a lens if the object distance is 20 cm and the image distance is 10 cm?

What is the magnification produced by a lens if the object distance is 20 cm and the image distance is 10 cm?

Step 1: Identify the object distance (u) and the image distance (v). Here, u = 20 cm and v = 10 cm.
Step 2: Use the magnification formula, which is m = -v/u.
Step 3: Substitute the values into the formula: m = -10/20.
Step 4: Calculate the value: -10 divided by 20 equals -0.5.
Step 5: Since magnification is often expressed as an absolute value, take the absolute value of -0.5, which is 0.5.
Step 6: To express magnification in a more common way, we can say that the image is 2 times larger than the object, so we write m = 2.
