Physics · Reflection of light, spherical mirrors, mirror formula
Regular reflection takes place when light is incident on:
Regular reflection takes place when light is incident on:
- A. a rough curved surface
- B. a highly polished plane surface
- C. either of A and B
- D. neither of A and B
Step-by-step solution
Regular (specular) reflection requires a smooth surface where parallel incident rays remain parallel after reflection. A highly polished plane surface provides the necessary smoothness. A rough curved surface causes diffuse reflection, so only option B is correct.
