Question 1
What is the thin lens formula?
- 1/v + 1/u = 1/f
- 1/u - 1/v = 1/f
- 1/v + 1/f = 1/u
💡 Hint: Think about how lenses operate when light interacts with them.
Question 2
True or False: The lens maker's formula is only applicable to concave lenses.
- True
- False
💡 Hint: Consider both convex and concave types.
