Select from the following the best set-up for tracing the path of a ray of light through a rectangular glass slab:
Select from the following the best set-up for tracing the path of a ray of light through a rectangular glass slab:
Options
The best set-up for tracing the path of a ray of light through a rectangular glass slab is II.
Marking Scheme
- 11 mark for correct answer
Hint
Remember that light travels in straight lines until it encounters a medium with a different optical density, at which point it bends.
Quick Oral Answer
The best set-up for tracing the path of a ray of light through a rectangular glass slab is II because it shows the incident ray passing through the glass slab and emerging from the other side, which is the expected behavior of light when it passes through a transparent medium like glass.
Analysis & Explanation
This question requires the student to understand the concept of refraction and how it applies to a rectangular glass slab. The correct answer, II, shows the incident ray passing through the glass slab and emerging from the other side, which is the expected behavior of light when it passes through a transparent medium like glass. The other options do not accurately depict the path of the ray of light.
Common Mistakes
- 1thinking that the ray of light will not bend when passing through the glass slab
- 2not considering the change in medium
Interesting Facts
The angle of incidence is equal to the angle of refraction when light passes from one medium to another.
The speed of light changes when it passes from one medium to another.
