Q
Q: A lens produces a magnification of 3. If the object height is 2 cm, what is the image height?
Solution:
Magnification (m) = h'/h, thus h' = m * h = 3 * 2 = 6 cm.
Steps: 5
Show Steps
Step 1: Understand that magnification (m) is the ratio of the image height (h') to the object height (h).
Step 2: Write the formula for magnification: m = h' / h.
Step 3: Rearrange the formula to find the image height: h' = m * h.
Step 4: Substitute the given values into the formula: m = 3 and h = 2 cm.
Step 5: Calculate the image height: h' = 3 * 2 = 6 cm.
