Worked Solution & Example Answer:Figure 3 shows a ray of light going from air to glass - Edexcel - GCSE Physics - Question 3 - 2019 - Paper 1
Step 1
Fill in the labels
Answer
To correctly label the ray of light in Figure 3, we can use the terms provided in the box:
-
Incident Ray: This label represents the ray of light traveling from the air into the glass. It is the incoming ray before it interacts with the glass medium.
- Place the label 'incident' next to the ray that enters the glass.
-
Refracted Ray: This label corresponds to the ray of light that bends as it enters the glass medium due to a change in speed. It is the ray that exits into the glass.
- Place the label 'refracted' next to the ray that continues inside the glass.
-
Reflected Ray: This label indicates the ray of light that bounces back into the air after hitting the glass. The reflection occurs at the boundary between air and glass.
- Place the label 'reflected' next to the ray that returns to the air.
