Does curved mirror follow the law of reflection?

Yes, curved mirrors follow the law of reflection. The angle of incidence is equal to the angle of reflection at any point on the mirror's surface.


Is the optical axis parallel to the curved surface?

No. It's straight through the center of the sphere that the curved surface is part of.


Is it better to build a straight bridge or curved bridge out of toothpicks?

Are the laws of reflection applicable to plane surfaces also valid for curved surfaces?

Yes, the laws of reflection are applicable to curved surfaces as well. The angle of incidence is still equal to the angle of reflection, but both angles are measured with respect to the normal at the point of incidence on the curved surface.


Does the law of reflection apply to curved and flat mirrors?

The law of reflection is valid for any ray of light. So it is also valid for curved and flat surfaces. For curved surfaces, the normal is taken as the normal to the tangent of the point where the light ray hits the surface.


What are the necessary conditions for a surface to give an accurate reflection in the experiment of the laws of reflection?

The surface should be smooth and flat to give an accurate reflection in the laws of reflection experiment. A rough or curved surface may distort the reflection, making it difficult to observe and verify the angle of incidence equals the angle of reflection. Additionally, the surface should be clean and free from any dirt or smudges that could interfere with the reflection.


Would a shadow cast on Earth be straight or curved?

Well, if you had a shadow cast on earth, it would appear curved because the of the Earth's surface is curved


Why would a straight trimmer be better then a curved trimmer?

Straight trimmers give you more reach and have more power for cutting tall weeds. Curved trimmers are better for tight spaces.

Do a pyramid and cones have curved surfaces?

Yes, a cone has a curved surface, as it tapers smoothly from its circular base to a point at the top. In contrast, a pyramid has flat, polygonal faces and does not have a curved surface; its sides are made up of straight edges that meet at a vertex. Thus, only the cone exhibits a curved surface between its base and apex.
