Four modifications are suggested in the lens formula to include the effect of the thickness t of the lens. Which one is likely to be correct?
- A$\frac{1}{\text{v}}-\frac{1}{\text{u}}=\frac{1}{\text{uf}}$
- B$\frac{1}{\text{v}^2}-\frac{1}{\text{u}}=\frac{1}{\text{f}}$
- ✓$\frac{1}{\text{v}-\text{t}}-\frac{1}{\text{u}+\text{t}}=\frac{1}{\text{f}}$
- D$\frac{1}{\text{v}}-\frac{1}{\text{u}}+\frac{\text{t}}{\text{uv}}=\frac{\text{t}}{\text{f}}$
