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 of a telescope serves two primary functions. Firstly, it magnifies the real image produced by the objective lens, allowing for a clearer and enlarged view of distant objects. Secondly, it enhances the detail seen in the image, making it easier for the viewer to focus on specific points of interest.
Step 2
Suggest how photographs would have helped Galileo.
Answer
Photographs would have made recording results easier and quicker for Galileo. Instead of manually drawing observations, he could have captured images instantly, providing more accurate and reliable evidence of his findings about Jupiter and its moons.
