An individual's eye pupil changes from a diameter of 1.5 mm to 3.5 mm as the illumination is increased. By what factor does the minimum angle of resolution change?
A microscope has an objective lens with an aperture of diameter 0.60 cm where a monochromatic light source of wavelength 580 nm is used to illuminate the object. It is determined that the minimum angle of resolution is 1.18 104 rad. If the illuminating source were replaced by a source of wavelength 700 nm, what would the minimum angle of resolution now become? (1 nm = 109 m)
A) 0.58 104 rad
B) 1.4 104 rad
C) 0.85 104 rad
D) 1.2 104 rad
If different filters are used with an astronomical telescope, which of the following would give the best resolution?
D) All yield the same resolution.
The 2.4-m diameter Hubble space telescope has been placed into Earth orbit by the space shuttle. Assuming a wavelength of 710 nm, what angular resolution could this telescope achieve by Rayleigh's criterion? (1 nm = 109 m)
A) 5.7 106 rad
B) 7.5 106 rad
C) 3.6 107 rad
D) 2.5 107 rad
