NYSTCE CST Physics - Exam Topics Sample Questions

If a person is looking through a telescope at the full moon, how would the appearance of the moon change if half of the objective lens was covered?

Correct Answer:
brightness will reduce


when observing the full moon through a telescope, if half of the objective lens is covered, the most significant change would be a reduction in the brightness of the moon's appearance. this effect occurs due to the direct relationship between the aperture size of the telescope's objective lens and the intensity of light that it can collect.

the objective lens in a telescope is primarily responsible for gathering light from the celestial object being observed and focusing it to form an image. the size of the objective lens, often referred to as the aperture, determines how much light the telescope can capture. a larger aperture allows more light to enter, which not only improves brightness but also enhances the overall resolution and detail of the image.

covering half of the objective lens effectively reduces the aperture's size by half. as a result, the amount of light collected from the moon is also halved. this decrease in light collection leads directly to a dimmer image of the moon. it's important to note that while the brightness of the image is reduced, the actual field of view and the completeness of the lunar image remain unaffected. the entire moon will still be visible, but it will appear less bright than it would with the full aperture in use.

contrary to what some might expect, covering part of the lens does not result in seeing only half of the moon or any part of the moon being blocked out in the view. the reason for this is that telescopes create an image by focusing light rays from the entire visible surface of the celestial object into the eyepiece. as long as there is enough aperture to collect and focus light from the entire object, the entire object will be visible in the viewer, albeit with reduced intensity.

in summary, while covering half of the objective lens of a telescope when viewing the full moon does not obstruct part of the moon from view, it significantly reduces the brightness of the image seen through the eyepiece. this reduction in brightness is due to the decreased light-gathering capability of the telescope caused by the partial covering of the objective lens.
