An astronomer is trying to observe two distant stars. The stars are marginally resolved when she looks at them through a filter that passes green light with a wavelength near 550 nm. Which of the following actions would improve the resolution? Assume that the resolution is not limited by the atmosphere.
Required:
a. Changing the filter to a different wavelength? If so, should she use a shorter or a longer wavelength?
b. Using a telescope with an object lens of the same diameter but a different focal length? If so, should she select a shorter or a longer focal length?
c. Using a telescope with an objective lens of the same focal length but a different diameter? If so, should she select a larger or a smaller diameter?
d. Using an eyepiece with a different magnification? If so, should she select an eyepiece with more or less magnification?
