Which of the following actions would improve the resolution if 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. Assume that the resolution is not limited by the atmosphere. 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 objective 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?
