Question
A ray of light undergoes ______ when it encounters more than one transparent mediums placed one after the other.
- Refraction
- Multiple refractions
- Reflection
- Multiple reflections
Hint:
Think about the phenomenon of light where medium or refractive index changes.
The correct answer is: Multiple refractions
- “Refraction is the change in the direction of a wave passing from one medium to another."
- So when multiple mediums are there it will face Multiple Refractions.
