Worked Solution & Example Answer:The diagram shows a telescope consisting of two converging lenses - Edexcel - GCSE Physics - Question 5 - 2016 - Paper 1
Step 1
Which position on the diagram shows where the real image of the Moon is formed?
Answer
The real image of the Moon produced by the objective lens is formed at position Y. This is because the objective lens, being a converging lens, focuses light from the Moon to create a real image at the focal point, which aligns with position Y in the diagram.
Step 2
Describe the function of the eyepiece lens.
Answer
The eyepiece lens in a telescope magnifies the image produced by the objective lens, allowing for a clearer and larger view of the Moon. It acts as a magnifying glass that increases the angle of view for the observer, providing better detail and clarity. The eyepiece lens also helps to focus the light into the eye, enhancing the overall observation experience.
