While performing the experiment on tracing the path of a ray of light through a rectangular glass slab, in which of the following experimental set-ups is a student likely to get best results? (P₁ and P₂ are the positions of the pins fixed for the experiment)
While performing the experiment on tracing the path of a ray of light through a rectangular glass slab, in which of the following experimental set-ups is a student likely to get best results? (P₁ and P₂ are the positions of the pins fixed for the experiment)
Options
The best results for tracing the path of a ray of light through a rectangular glass slab would be obtained with experimental set-up I.
Marking Scheme
- 11 mark for correct answer
Hint
To get the best results, the pins P1 and P2 should be placed in such a way that the incident ray of light passes through the center of the glass slab.
Quick Oral Answer
The best results for tracing the path of a ray of light through a rectangular glass slab would be obtained with experimental set-up I because it allows for the most accurate tracing of the path of the ray of light.
Analysis & Explanation
The correct answer is A because the experimental set-up I allows for the most accurate tracing of the path of the ray of light through the glass slab. The other options do not provide the same level of accuracy due to the placement of the pins P1 and P2.
Common Mistakes
- 1Placing the pins P1 and P2 at an angle to the glass slab
- 2Not ensuring that the incident ray of light passes through the center of the glass slab
Interesting Facts
The refractive index of a material is a measure of how much it bends light.
The angle of incidence is equal to the angle of refraction when light passes from one medium to another.
