Worked Solution & Example Answer:This question is about reflection and refraction of light - Edexcel - GCSE Physics - Question 3 - 2022 - Paper 1
Step 1
Draw the ray of light after it reflects off the mirror surface.
Answer
To draw the reflected ray:
- Start at the point where the incoming ray strikes the mirror.
- Draw the reflected ray at an angle equal to the angle of incidence.
- Label this angle clearly, ensuring it follows the law of reflection: the angle of reflection equals the angle of incidence.
Step 2
Draw the ray of light after it refracts at the surface of the glass block.
Answer
To draw the refracted ray:
- Indicate the incoming ray striking the glass block.
- Draw the refracted ray bending towards the normal, as light travels from air to glass.
- Ensure that the angle of refraction is less than the angle of incidence, which indicates the light is slowing down as it enters the denser medium.
