## Physics for Scientists and Engineers: A Strategic Approach with Modern Physics (4th Edition)

We can write an equation for the resolution: $\theta_{min} = \frac{1.22~\lambda}{D}$ a. Decreasing the wavelength causes $\theta_{min}$ to decrease. Therefore, decreasing the wavelength would improve the resolution. b. The resolution does not depend on the focal length. c. Increasing the lens diameter causes $\theta_{min}$ to decrease. Therefore, increasing the lens diameter would improve the resolution. d. The resolution does not depend on the magnification.
