Step 1
Step 1: The lens formula is given by: $$ \frac{1}{f} = \frac{1}{u} + \frac{1}{v}$$ where f is the focal length, u is the object distance, and v is the image distance. Show more…

The relation between the object distance u, the image distance v, and the focal length f of a thin lens is 1/u + 1/v = 1/f. 1. What is the relation for f in terms of u and v? [2 marks] 2. Using this expression and calculus, calculate the greatest possible error in estimating f and the corresponding percentage error if the measured values of u and v are u = 0.31 (± 0.01) and v = 0.56 (± 0.03). [8 marks]

If u = v = 30 cm, the focal length of the lens is 15 cm 10 cm 25 cm 20 cm
Use the formulas $\frac{1}{f}=\frac{1}{s_{o}}+\frac{1}{s_{i}}$ and $M=\frac{h_{i}}{h_{o}}=\frac{-s_{i}}{s_{o}}$ for Problems 1-8. Given $s_{o}=7.35 \mathrm{~cm}$ and $s_{i}=17.0 \mathrm{~cm},$ find $f$
