Worked Solution & Example Answer:1. (a) Which ray diagram shows total internal reflection at an air and glass boundary? (1) (b) Figure 1 is a ray diagram for a converging lens used as a magnifying glass - Edexcel - GCSE Physics - Question 1 - 2022 - Paper 1
Step 1
(b)(i) Using information from Figure 1, determine the magnification of the virtual image.
Answer
To find the magnification of the virtual image, we use the formula:
Given the heights from Figure 1 (assuming the heights are labeled or can be measured from the diagram), substitute those values into the equation to find the magnification.
Step 2
(b)(ii) Describe one way the magnification of the image could be increased.
Answer
One way to increase the magnification of the image is to use a different lens or replace the current lens with one that has a higher power or shorter focal length. This change enhances the curvature of the lens and increases the refractive index, leading to a larger virtual image.
