Q: What is the magnification produced by a concave lens if the object distance is 20 cm and the image distance is -10 cm?
Solution:
Magnification m = -v/u = -(-10)/20 = 0.5.
Steps: 6
Show Steps
Step 1: Identify the object distance (u). In this case, u = 20 cm.
Step 2: Identify the image distance (v). Here, v = -10 cm (the negative sign indicates that the image is virtual).
Step 3: Use the magnification formula: m = -v/u.
Step 4: Substitute the values into the formula: m = -(-10)/20.
Step 5: Simplify the equation: m = 10/20.
Step 6: Calculate the final result: m = 0.5.
