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 is formed at position Y. In a telescope, the objective lens produces a real image of the distant object, which in this case is the Moon. The real image is typically formed between the two lenses.
Step 2
Describe the function of the eyepiece lens.
Answer
The eyepiece lens is designed to magnify the image produced by the objective lens. It allows the viewer to see a larger, clearer version of the real image of the Moon. The eyepiece lens works by gathering light from the real image and further refracting it, enabling the viewer to observe the details of the image more clearly.
