Worked Solution & Example Answer:This picture shows Galileo holding a telescope - Edexcel - GCSE Physics - Question 5 - 2014 - Paper 1
Step 1
Explain the purpose of the eyepiece in a telescope.
Answer
The eyepiece in a telescope serves primarily to magnify the image produced by the objective lens. It allows the observer to see a larger version of the distant object being viewed. Additionally, it helps in providing greater detail of the image focused at the focal point of the telescope, making the view clearer and more focused by inverting the image for accurate observation.
Step 2
Suggest how photographs would have helped Galileo.
Answer
Photographs would have assisted Galileo by making recording observations easier and quicker. Instead of having to manually draw observations, he could capture images of celestial bodies for more accurate and precise documentation. Additionally, photographs would provide better proof of his findings, as they could be shared with others, lending credibility to his claims about Jupiter's moons and their movements.
