Estimate the linear separation of two objects that the human eye
can resolve at a distance of 1 meter. Take the diameter of the pupil
to be 5 mm, and the wavelength of the light to be 420 nm.
An astronaut in a space shuttle claims she can just barely resolve two point sources on Earth’s surface, 160 km below. Calculate their (a) angular and (b) linear separation, assuming ideal conditions.Take l = 540 nm and the pupil diameter of the astronaut’s eye to be 5.0 mm.
Estimate the linear separation (in kilometers) of two objects at a distance of 9.6 × 108 km that can just be resolved by an observer on
Earth (a) using the naked eye and (b) using a telescope with a 6.2-m diameter mirror. Use the following data: diameter of pupil = 5.0
mm; wavelength of light = 550 nm.
