The camera on a spy satellite has a lens with a diameter of 1.5 m. This satellite is in low-Earth orbit about 2.9 x 10⁵ m above the surface of the Earth. (See Chapter 5, Eq. 5.28.) What is the approximate size of the smallest feature the camera can resolve when taking a picture of something on the Earth’s surface? Assume blue light with a wavelength of 400 nm. Ignore the effect of the Earth’s atmosphere on the resolution.
