For a spacecraft with an exterior surface made of metal, sunlight could cause the surface to become positively charged due to the photoelectric effect and this in turn can damage the delicate electronics inside. Work function /(10-1⁹ J) Material platinum lead titanium 10.2 6.63 6.94 For sunlight with a wavelength of 284 nm, we need to decide which of the above metals should be chosen for construction of the spacecraft where it will be subject to lots of these photons while in orbit. a. The photon energy is J.
