Question
A ray of light strikes normally on the surface of a mirror. The reflected ray _____.
- Goes along the normal
- Makes an angle of 30 degrees with the normal
- Goes along the surface
- Does not emerge
Hint:
The natural phenomenon that occurs when a ray of light hits a surface is called light reflection. Light hitting a rough surface will be reflected at a different angle, while light hitting a smooth surface will be reflected at the same angle. The mirror has a smooth surface.
The correct answer is: Goes along the normal
- Reflection is defined as the natural phenomenon associated with the bouncing of light rays when they hit a surface.
- When the beam hits the mirror, most of the light is reflected. The angle at which a ray hits a reflective surface is called the angle of incidence.
- The angle at which light is reflected is called the angle of reflection.
- So, when a ray of light hits the surface of the mirror, it must be reflected according to the principle of reflection.
