Question
Which of the following does not exist physically
- Incident ray
- Reflected ray
- Normal
- Reflecting surface
Hint:
The normal does not exist physically.
The correct answer is: Normal
- In a reflecting area, the incident ray and normal ray are measured to be physically present.
- The normal in the surface is a middle perpendicular line from the surface of reflection.
- It does not physically exist.
